Association of statins with nonalcoholic fatty liver disease in patients with diabetes.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in patients with diabetes; limited data suggested that statins may reduce the risk of NAFLD progression. This study aimed to examine the association between statins and the development or progression of NAFLD in veterans with diabetes. In a new-user negative control design, we conducted a retrospective propensity score (PS)-matched cohort study of patients with diabetes between 2003 and 2015. After excluding patients with other causes of liver disease, we formed PS using 85 characteristics. The primary outcome was a composite NAFLD progression outcome. Primary analysis examined odds of outcome in PS-matched cohort. Post-hoc analysis included a PS-matched cohort of statin users with intensive lowering of low-density lipoprotein-cholesterol (LDL-C) vs low-intensity lowering. We matched 34,102 pairs from 300,739 statin users and 38,038 non-users. The composite outcome occurred in 8.8% of statin users and 8.6% of non-users (odds ratio (OR) 1.02, 95% confidence interval (95% CI) 0.97-1.08). In the post-hoc analysis, intensive lowering of LDL-C compared to low-intensity showed increased NAFLD progression (OR 1.21, 95% CI 1.13-1.30). This study showed that statin use in patients with diabetes was not associated with decreased or increased risk of NAFLD progression. Intensive LDL-C lowering, compared to low-intensity LDL-C lowering, was associated with an increased risk of NAFLD progression.

Association of Strict Versus Lenient Cholesterol Lowering with Cardiac Outcomes, Diabetes Progression and Complications, and Mortality in Patients with Diabetes Treated with Statins: Is Less More?

INTRODUCTION: Whereas some guidelines recommend statin use to achieve low-density lipoprotein cholesterol (LDL-C) goal < 70 mg/dL for primary prevention of atherosclerotic cardiovascular disease (ASCVD) in patients at higher risk, others recommend against a target LDL-C level. Achieving a target level < 70 mg/dL commonly requires the use of high intensity statins, which has been associated with higher risk of diabetes progression. The objective of this study is to assess the association of strict (≤ 70 mg/dL) versus lenient (> 70 to100 mg/dL) LDL-C lowering on major adverse cardiovascular events (MACE), diabetes progression, diabetes microvascular complications, and total mortality in patients with diabetes. METHODS: This was a retrospective propensity score (PS)-matched study from a national cohort of, predominantly male, veterans diagnosed with diabetes without prior cardiovascular disease (from fiscal years 2003-2015), who were initiated on a statin. We created PS to match strict (mean LDL-C during follow-up ≤ 70 mg/dL) versus lenient (mean LDL-C during follow up > 70-100 mg/dL) using 65 baseline characteristics including comorbidities, risk scores, medication classes usage, vital signs, and laboratory data. Outcomes included MACE, diabetes progression, microvascular diabetes complications, and total mortality. RESULTS: From 80,110 eligible patients, we PS-matched 21,294 pairs of statin initiators with strict or lenient LDL-C lowering. The mean (SD) age was 64 (9.5) years and mean (SD) duration of follow-up was 6 (3) years. MACE was similar in the PS-matched groups [6.1% in strict versus 5.8% in lenient; odds ratio (OR): 1.06; 95% confidence interval (95% CI) 0.98-1.15, P = 0.17]. Diabetes progression was higher among the strict vs lenient group (66.7% in strict versus 64.1% in lenient; OR 1.12; 95% CI 1.08-1.17, P < 0.001). There was no difference in microvascular diabetes complications (22.3% in strict versus 21.9% in lenient; OR 1.02; 95% CI 0.98-1.07, P = 0.31) and no difference in total mortality (14.6% in strict versus 15% in lenient; OR 0.97; 95% CI 0.92-1.02, P = 0.20). CONCLUSION: Strict compared with lenient lowering of LDL-C with statins in men with diabetes without preexisting ASCVD did not decrease the risk of MACE but was associated with an increased diabetes progression. Clinicians should monitor their patients for diabetes progression upon escalating statins to achieve LDL-C levels ≤ 70 mg/dL.

Association of Thiazide Diuretics With Diabetes Progression, Kidney Disease Progression, Cardiovascular Outcomes, and Death Among Patients With Diabetes Who Initiate Statins.

Statins have been associated with diabetes mellitus (DM) progression but their cardiovascular benefit in patients with DM outweigh the harm. However, the effects of concurrent use of other medications that similarly increase blood glucose level, such as thiazide diuretics, are not well studied. This study aimed to evaluate the association of concurrent use of thiazide diuretics and statins on DM progression, cardiovascular and renal outcomes, and death in patients with DM. This is a retrospective cohort study of Veterans with DM who initiated statins between 2003 and 2015. The cohort comprised thiazide users (concomitantly used thiazides and statins for ≥6 months) and active comparators (concomitantly used calciun channel blockers [CCB] but not thiazides and statins for ≥6 months). We excluded patients who were <18 years old, with chronic kidney disease stage 4 or worse, or used loop diuretics. We propensity-score-matched comparison groups on 99 baseline characteristics including demographics, healthcare utilization, co-morbidities, cardiovascular and co-morbidity scores, vital signs, laboratory data, and medication class usage. Outcomes were: (1) DM progression (new insulin initiation, increase in the number of glucose-lowering medication classes, and hyperglycemic episodes); (2) kidney disease progression (doubling of serum creatinine, incidence of chronic kidney disease stage 5, initiation of renal replacement therapy, and incidence of diabetic nephropathy); (3) cardiovascular outcomes (acute myocardial infarction, stroke, cardiac arrest); and (4) total mortality. From 297,967 statin users (228,509 Thiazide-statin users and 69,458 active comparators), we successfully matched 67,614 pairs. In comparison to active comparators, thiazide-statin users had increased risk of DM progression (65.6% in CCB group vs 68.1% in thiazide group; odds ratio [OR]: 1.12, 95% confidence interval [CI]: 1.09 to 1.15), decreased risk of kidney progression (16.9% in CCB group vs 16.5 in thiazide group; OR: 0.97, 95% CI: 0.94 to 0.99), decreased risk of cardiovascular outcomes (15.7% in CCB group vs 14.6% in thiazide group; OR: 0.92, 95% CI: 0.89 to 0.95), and similar risk of total mortality (19.7% in each group; OR: 1.00, 95% CI: 0.98 to 1.03). This study attempted to answer an important clinical question whether thiazide diuretics should be discontinued or substituted upon statin initiation. Our results showed that concurrent use of statin and thiazides in patients with DM was associated with DM progression but with less kidney progression and cardiovascular outcomes and no difference in mortality. Clinicians should closely monitor DM control when thiazides and statins are used concurrently.

Significance of Chronic Kidney Disease on Morbidity and Mortality in Hospitalized Patients With COVID-19.

Background: Patients with comorbid illnesses are at risk for worse outcomes with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; COVID-19). Our research examined patients with chronic kidney disease (CKD) to establish whether it remains an independent risk factor for mortality and morbidity in patients with COVID-19. Methods: We conducted a retrospective cohort study using an electronic patient database in 2020. An observational dataset from 149 hospitals comprising a United States-based health system (HCA Healthcare) was analyzed. Hospitalized patients (N=11 086), aged 18 and above, with a COVID-19 polymerase chain reaction positive result between January 1, 2020, and September 1, 2020, were included in the initial data set.Primary outcomes were in-hospital death or discharge to hospice in patients with COVID-19. Secondary outcomes were individual components of the primary outcome including intensive care unit (ICU) admission, ventilator dependency, development of acute kidney injury (AKI), and in-hospital death. Baseline patient characteristics were recorded, including demographic variables and comorbidities. Results: A total of 11 086 patients were included in the analysis. The study group included patients with CKD (5543 patients). Patients in the control group (5543 patients) were propensity matched for age, race, sex, and ethnicity. The primary outcome of in-hospital death or discharge to hospice was observed in 20.96% of patients with CKD compared to 11.91% of the control group with an odds ratio of 1.58 (confidence interval 1.37-1.80). ICU admission was required for 37.20% of patients in the CKD group and 21.63% of patients in the control group (P < .001). Ventilator dependency was found in 14.41% of patients in the CKD group and 8.59% of patients in the control group (P < .01). Development of AKI was seen in 5.65% of patients in the CKD group and 2.90% of patients in the control group (P < .01). A logistic regression model confirmed an independent association between underlying CKD and in-hospital death or discharge to hospice in patients with COVID-19. Conclusion: Our study confirms an independent association between underlying CKD and poor outcomes among hospitalized patients with COVID-19, including in-hospital death or discharge to hospice.

Statins and renal disease progression, ophthalmic manifestations, and neurological manifestations in veterans with diabetes: A retrospective cohort study.

BACKGROUND: Statins increase insulin resistance, which may increase risk of diabetic microvascular complications. Little is known about the impact of statins on renal, ophthalmologic, and neurologic complications of diabetes in practice. The objective of this study was to examine the association of statins with renal disease progression, ophthalmic manifestations, and neurological manifestations in diabetes. METHODS: This is a retrospective cohort study, new-user active comparator design, that included a national Veterans Health Administration (VA) patients with diabetes from 2003 to 2015. Patients were age 30 years or older and were regular users of the VA with data encompassing clinical encounters, demographics, vital signs, laboratory tests, and medications. Patients were divided into statin users or nonusers (active comparators). Statin users initiated statins and nonusers initiated H2-blockers or proton pump-inhibitors (H2-PPI) as an active comparator. Study outcomes were: 1) Composite renal disease progression outcome; 2) Incident diabetes with ophthalmic manifestations; and 3) Incident diabetes with neurological manifestations. RESULTS: Out of 705,774 eligible patients, we propensity score matched 81,146 pairs of statin users and active comparators. Over a mean (standard deviation) of follow up duration of 4.8 (3) years, renal disease progression occurred in 9.5% of statin users vs 8.3% of nonusers (odds ratio [OR]: 1.16; 95% confidence interval [95%CI]: 1.12-1.20), incident ophthalmic manifestations in 2.7% of statin users vs 2.0% of nonusers (OR: 1.35, 95%CI:1.27-1.44), and incident neurological manifestations in 6.7% of statin users vs 5.7% of nonusers (OR: 1.19, 95%CI:1.15-1.25). Secondary, sensitivity, and post-hoc analyses were consistent and demonstrated highest risks among the healthier subgroup and those with intensive lowering of LDL-cholesterol. CONCLUSIONS: Statin use in patients with diabetes was associated with modestly higher risk of renal disease progression, incident ophthalmic, and neurological manifestations. More research is needed to assess the overall harm/benefit balance for statins in the lower risk populations with diabetes and those who receive intensive statin therapy.

Association of Statin Therapy Initiation With Diabetes Progression: A Retrospective Matched-Cohort Study.

Importance: Statin therapy has been associated with increased insulin resistance; however, its clinical implications for diabetes control among patients with diabetes is unknown. Objective: To assess diabetes progression after initiation of statin use in patients with diabetes. Design, Setting, and Participants: This was a retrospective matched-cohort study using new-user and active-comparator designs to assess associations between statin initiation and diabetes progression in a national cohort of patients covered by the US Department of Veterans Affairs from fiscal years 2003-2015. Patients included were 30 years or older; had been diagnosed with diabetes during the study period; and were regular users of the Veterans Affairs health system, with records of demographic information, clinical encounters, vital signs, laboratory data, and medication usage. Interventions: Treatment initiation with statins (statin users) or with H2-blockers or proton pump inhibitors (active comparators). Main Outcomes and Measures: Diabetes progression composite outcome comprised the following: new insulin initiation, increase in the number of glucose-lowering medication classes, incidence of 5 or more measurements of blood glucose of 200 mg/dL or greater, or a new diagnosis of ketoacidosis or uncontrolled diabetes. Results: From the 705 774 eligible patients, we matched 83 022 pairs of statin users and active comparators; the matched cohort had a mean (SD) age of 60.1 (11.6) years; 78 712 (94.9%) were men; 1715 (2.1%) were American Indian/Pacific Islander/Alaska Native, 570 (0.8%) were Asian, 17 890 (21.5%) were Black, and 56 633 (68.2 %) were White individuals. Diabetes progression outcome occurred in 55.9% of statin users vs 48.0% of active comparators (odds ratio, 1.37; 95% CI, 1.35-1.40; P < .001). Each individual component of the composite outcome was significantly higher among statin users. Secondary analysis demonstrated a dose-response relationship with a higher intensity of low-density lipoprotein-cholesterol lowering associated with greater diabetes progression. Conclusions and Relevance: This retrospective matched-cohort study found that statin use was associated with diabetes progression, including greater likelihood of insulin treatment initiation, significant hyperglycemia, acute glycemic complications, and an increased number of prescriptions for glucose-lowering medication classes. The risk-benefit ratio of statin use in patients with diabetes should take into consideration its metabolic effects.

Is Statin Use Associated With Risk of Thyroid Diseases? Results of a Retrospective Cohort Study.

BACKGROUND: Given the ubiquity of statin use and prevalence of thyroid diseases, such as thyroid cancer, hyperthyroidism, and thyroiditis, understanding their association deserves further attention. OBJECTIVE: To examine the association between statin use and thyroid cancer, thyrotoxicosis, goiter, and thyroiditis. METHODS: Using Tricare data, 2 propensity score (PS)-matched cohorts of statin users and nonusers were formed: (1) a PS-matched general cohort (all patients aged 30-85 years) and (2) a PS-matched healthy cohort (excluded patients with cardiovascular diseases or severe comorbidities). Outcomes were thyroid cancer, thyrotoxicosis, goiter, and thyroiditis. Odds ratios (ORs) and 95% CIs of outcomes were estimated using conditional regression analysis. RESULTS: Of 43 438 patients, the PS-matched general cohort matched 6342 statin users to 6342 nonusers. The OR of thyroid cancer was 0.62 (95% CI = 0.39-0.996). There was no significant difference between statin users and nonusers in risk of thyrotoxicosis (OR = 0.88; 95% CI = 0.71-1.09), goiter (OR = 0.9; 95% CI = 0.77-1.03), or thyroiditis (OR = 0.78; 95% CI = 0.53-1.15). In the PS-matched healthy cohort (3351 statin users to 3351 nonusers), there was no difference between statin users and nonusers in any outcome. Limitations of the study include its retrospective observational design and use of administrative codes in outcomes ascertainment. CONCLUSION AND RELEVANCE: This study did not demonstrate any association of statins with harmful effects on thyroid diseases, which offers assurance to clinicians and patients. Furthermore, statin use appears to be associated with a decreased risk of thyroid cancer, but more studies are needed.

Association of Breast Implants with Nonspecific Symptoms, Connective Tissue Diseases, and Allergic Reactions: A Retrospective Cohort Analysis.

BACKGROUND: Given the rising media attention regarding various adverse conditions attributed to breast implants, the authors examined the association between breast implantation and the risk of being diagnosed with connective tissue diseases, allergic reactions, and nonspecific constitutional complaints in a cohort study with longitudinal follow-up. METHODS: Women enrolled in a regional military health care system between 2003 and 2012 were evaluated in this retrospective cohort study. A propensity score was generated to match women who underwent breast implantation with women who did not undergo breast implantation. The propensity score included age, social history, health care use, comorbidities, and medication use. Outcomes assessed included International Classification of Diseases, Ninth Revision, diagnoses codes for (1) nonspecific constitutional symptoms, (2) nonspecific cardiac conditions, (3) rheumatoid arthritis and systemic lupus erythematosus, (4) other connective tissue diseases, and (5) allergic reactions. RESULTS: Of 22,063 women included in the study (513 breast implants and 21,550 controls), we propensity score-matched 452 breast implant recipients with 452 nonrecipients. Odds ratios and 95 percent confidence intervals in breast implant recipients compared to nonrecipients were similar, including nonspecific constitutional symptoms (OR, 0.77; 95 percent CI, 0.53 to 1.13), nonspecific cardiac conditions (OR, 0.97; 95 percent CI, 0.69 to 1.37), rheumatoid arthritis and systemic lupus erythematosus (OR, 0.66; 95 percent CI, 0.33 to 1.31), other connective tissue diseases (OR, 1.02; 95 percent CI, 0.78 to 1.32), and allergic reactions (OR, 1.18; 95 percent CI, 0.84 to 1.66). CONCLUSIONS: Women with breast implants did not have an increased likelihood of being diagnosed with nonspecific constitutional symptoms, connective tissue disorders, and/or allergic reaction conditions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

The Clot Thickens: Diagnosing Acute Pulmonary Embolism as a Trigger for Chronic Obstructive Pulmonary Disease Exacerbation in the Setting of Anticoagulation Failure.

Chronic obstructive pulmonary disease (COPD) exacerbations are most commonly triggered by infections, but up to 25% of those that require hospitalization are thought to be triggered by acute pulmonary embolism. We present the case of a 71-year-old patient with a history of unprovoked pulmonary embolisms on anticoagulation therapy hospitalized for a COPD exacerbation. The exacerbation was triggered by an acute pulmonary embolism, representing anticoagulation failure. LEARNING POINTS: Pulmonary embolism (PE) is an important trigger of COPD exacerbations and should be considered, especially when there is an unexplained abrupt or recurrent increase in the frequency or severity of exacerbations.Therapeutic anticoagulation does not preclude the presence of PE.Clinical risk stratification is a crucial component of medical decision-making.

Statins in survivors of traumatic brain injury: a propensity score-matched analysis.

BACKGROUND: Several in-vitro and animal studies suggest that statins may have beneficial effects on clinical outcomes of traumatic brain injury (TBI), however, clinical data are scarce. OBJECTIVES: To examine the association of statin use with TBI clinical outcomes among patients with TBI. METHODS: A retrospective cohort study of Tricare beneficiaries who had a TBI diagnosis, as defined by the Barbell injury diagnosis matrix. Outcomes were defined using ICD-9 codes and included: post-concussion syndrome, neurological disorders, substance dependence or abuse, and psychiatric disorders. Statin-users and non-users were propensity score (PS)-matched using 103 baseline characteristics. RESULTS: Out of 1187 adult patients with a TBI diagnosis (172 statin-users and 1015 nonusers), we PS-matched 70 statin-users to 70 non-users. There were no statistically significant differences in the PS-matched cohort of statin-users in comparison to nonusers for post-concussion syndrome (odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.03-2.20), neurological disorders (OR: 0.60, CI: 0.31-1.16); substance dependence or abuse (OR: 0.80, CI: 0.40-1.60), or psychiatric disorders (OR 0.80, CI: 0.41-1.55). CONCLUSION: This study did not show benefit or harm for statins among survivors of TBI. Our findings do not support the evidence from some animal studies and small randomized controlled trials. Further studies utilizing larger sample sizes are warranted.

Statin use and medically attended acute respiratory illness among influenza vaccine recipients.

BACKGROUND: Previous studies have suggested that statins decrease influenza vaccine effectiveness and increase risk of medically attended acute respiratory illness (MAARI). OBJECTIVES: To examine the association of incident statin use and MAARI in a cohort of influenza vaccine recipients. METHODS: This retrospective cohort study evaluated influenza vaccine recipients within the Tricare population. The primary outcome compared MAARI incidence during the follow-up period in a propensity score-matched cohort of incident statin users and statin non-users. Secondary analysis included propensity score-adjusted comparisons between incident statin users and statin non-users in the entire cohort and prespecified sub-cohorts with and without comorbidities. The propensity score was derived from 72 variables encompassing demographics, medical history, comorbidities, medication use, and healthcare utilization. RESULTS: MAARI incidence in statin users was similar to non-users in the propensity score-matched cohort (odds ratio [OR] 0.92; 95% confidence interval [CI] 0.84-1.01). In contrast, statin users with lower comorbidity had lower OR for MAARI compared to non-users (Charlson Score zero cohort: 0.85 [CI 0.74-0.98]; No Diabetes cohort: 0.88 [CI 0.80-0.96]). CONCLUSION: Incident statin use was not associated with increased MAARI incidence and may be associated with lower incidence of MAARI in those with less comorbidity. This study thus offers reassurance regarding the effectiveness of the influenza vaccine in statin users.

Association of Statin Use with Increased Risk of Musculoskeletal Conditions: A Retrospective Cohort Study.

INTRODUCTION: Musculoskeletal conditions, including osteoarthritis (OA), result in tremendous disability and cost. Statins are among the most commonly prescribed medications and their use for primary prevention in many otherwise healthy individuals, including those who are physically active, is increasing. There is conflicting evidence regarding the relationship of statin use and musculoskeletal conditions. Given the rising disability associated with musculoskeletal conditions, understanding predisposing factors, including medication-related exposures, deserves further attention. OBJECTIVES: We examined the association between statin use and the risk of being diagnosed with non-traumatic arthropathies, use-related injury, and undergoing rehabilitation in a cohort with longitudinal follow-up. METHODS: Patients enrolled in a regional military healthcare system between 2003 and 2012 were evaluated in this retrospective cohort study. A propensity score was generated to match statin-users and nonusers using 115 baseline characteristics. Outcomes included ICD-9 diagnoses codes for Agency for Healthcare Research and Quality disease categories of: non-traumatic arthropathies, use-related injury and undergoing rehabilitation. Primary analysis examined the outcomes in statin-users and nonusers after propensity score matching using conditional logistic regression analysis. RESULTS: Initially, 60,455 patients were identified. We propensity score-matched 6728 statin users with 6728 nonusers (52 years of age, ~ 47% women). In the propensity score-matched cohort, non-traumatic arthropathies occurred in 59.8% of statin users and 56.0% of nonusers [odds ratio (OR) 1.17, 95% confidence interval (95% CI) 1.09-1.25] and use related injury occurred in 31.9% of statin users and 29.8% of nonusers (OR 1.11, 95% CI 1.03-1.19). There was no difference between statin users and nonusers undergoing rehabilitation (22.6% among statin users, 21.9% among nonusers, OR 1.04, 95% CI 0.96-1.13). CONCLUSION: Statin use was associated with a significant increased risk of non-traumatic arthropathies and use-related injury. Our results provide additional data that can inform patient and clinician conversations about the benefits and risks of statin use.

Association of Statin Therapy With Risk of Epilepsy in 2 Propensity Score-Matched Cohorts.

BACKGROUND: Studies have suggested that statins may have a neuroprotective effect against epilepsy. However, evidence from rat models and case reports have suggested an opposite effect. Overall data are limited. OBJECTIVE: To examine the association between statin use and epilepsy risk in a general population and in a healthy population (individuals with no severe comorbidities). METHODS: Patients were Tricare beneficiaries from October 2003 to March 2012. Based on patients' characteristics during baseline phase (fiscal year [FY] 2004-2005), 2 propensity score (PS)-matched cohorts of statin users and nonusers were formed: (1) a PS-matched general cohort and (2) a PS-matched healthy cohort. Our outcome was defined using inpatient or outpatient ICD-9 codes for epilepsy during the follow-up phase (FY 2006 to March 2012) in the cohorts of statin users and nonusers. RESULTS: The study included a total of 43 438 patients (13 626 statin users and 29 812 nonusers). The PS-matched general cohort matched 6342 statin users to 6342 nonusers; the odds ratio (OR) of epilepsy in this cohort during follow-up was 0.91; 95% CI = 0.67-1.23. The PS-matched healthy cohort matched 3351 statin users to 3351 nonusers; OR in the PS-matched healthy cohort during follow-up was 1.08; 95% CI = 0.64-1.83. CONCLUSIONS: This study did not demonstrate a significant beneficial or deleterious effect of statin use on risk of being diagnosed with epilepsy. Clinicians should not withhold statins, whenever indicated, in patients with epilepsy.

Do Statins Increase the Risk of Esophageal Conditions? Findings from Four Propensity Score-Matched Analyses.

BACKGROUND AND OBJECTIVE: Statins are commonly used medications. Whereas some observational studies suggested an association of statin use with Barrett's esophagus and some upper gastrointestinal symptoms, there is a dearth of data on the association of statins and common esophageal conditions such as gastroesophageal reflux disease and esophagitis. The aim of this study is to examine the association of statins with esophageal conditions. METHODS: This is a retrospective cohort study using regional military healthcare data (1 October, 2003 to 1 March, 2012). The primary analyses evaluated the odds of: esophagitis; symptoms of esophagitis; gastroesophageal reflux disease/dyspepsia; and esophageal complications of gastroesophageal reflux disease in four propensity score-matched cohorts of statin users and non-users (propensity score-overall, propensity score-healthy, propensity score-women, and propensity score-men cohorts). Secondary and sensitivity analyses were performed. RESULTS: In the propensity score-overall cohort (n = 12,684), statin users were more likely to be diagnosed with esophagitis (odds ratio 1.11, 95% confidence interval 1.01-1.22) and gastroesophageal reflux disease/dyspepsia (odds ratio 1.18, 95% confidence interval 1.10-1.27) compared with non-users. Similar findings were seen in the propensity score-healthy cohort and in the propensity score-men cohort. In the propensity score-women cohort, the odds of esophagitis was higher among statin users compared with non-users (odds ratio 1.16, 95% confidence interval 1.02-1.32) but other outcomes were not different. In sensitivity analyses, which excluded patients with obesity, statin use was not associated with an increased odds ratio of gastroesophageal reflux disease/dyspepsia. CONCLUSION: Statin therapy was associated with higher odds of being diagnosed with esophagitis and gastroesophageal reflux disease/dyspepsia. Further study is warranted to elucidate the potential role of statins in these commonly diagnosed esophageal conditions.
