OBJECTIVES: The objective of this study was to assess the frequency and types of conflict of interest (COI) disclosed by authors of primary studies of health policy and systems research (HPSR). DESIGN: We conducted a cross-sectional survey using standard systematic review methodology for study selection and data extraction. We conducted descriptive analyses. SETTING: We collected data from papers published in 2016 in 'health policy and service journals' category in Web of Science database. PARTICIPANTS: We included primary studies (eg, randomised controlled trials, cohort studies, qualitative studies) of HPSR published in English in 2016 peer-reviewed health policy and services journals. OUTCOME MEASURES: Reported COI disclosures including whether authors reported COI or not, form in which COI disclosures were provided, number of authors per paper who report any type of COI, number of authors per paper who report specific types and subtypes of COI. RESULTS: We included 200 eligible primary studies of which 132 (66%) included COI disclosure statements of authors. Of the 132 studies, 19 (14%) had at least one author reporting at least one type of COI and the most frequently reported type was individual financial COI (n=15, 11%). None of the authors reported individual intellectual COIs or personal COIs. Financial and individual COIs were reported more frequently compared with non-financial and institutional COIs. CONCLUSION: A low percentage of HPSR primary studies included authors reporting COI. Non-financial or institutional COIs were the least reported types of COI.

BACKGROUND: Armed conflicts are increasingly impacting countries with a high burden of cancer. The aim of this study is to systematically review the literature on the impact of armed conflict on cancer in low- and middle-income countries (LMICs). METHODS: In November 2019, we searched five medical databases (Embase, Medline, Global Health, PsychINFO and the Web of Science) without date, language or study design restrictions. We included studies assessing the association between armed conflict and any cancer among civilian populations in LMICs. We systematically re-analysed the data from original studies and assessed quality using the Newcastle-Ottawa Scale. Data were analysed descriptively by cancer site. RESULTS: Of 1,543 citations screened, we included 20 studies assessing 8 armed conflicts and 13 site-specific cancers (total study population: 70,172). Two-thirds of the studies were of low methodological quality (score <5) and their findings were often conflicting. However, among outcomes assessed by three or more studies, we found some evidence that armed conflict was associated with increases in the incidence and mortality of non-specific cancers, breast cancer and cervical cancer. Single studies reported a positive association between armed conflict and the incidence of stomach and testicular cancers, some as early as 3 years after the onset of conflict. Some studies reported a post-conflict impact on time to diagnosis. CONCLUSION: Our findings support the need for more rigorous longitudinal and cohort studies of populations in and immediately post-conflict to inform the development of basic packages of cancer services, and post-conflict cancer control planning and development.
