A declaração PRISMA 2020: diretriz atualizada para relatar revisões sistemáticas*

[RESUMO]. A declaração dos Principais Itens para Relatar Revisões Sistemáticas e Meta-análises (PRISMA), publicada em 2009, foi desenvolvida para ajudar revisores sistemáticos a relatar de forma transparente por que a revisão foi feita, os métodos empregados e o que os autores encontraram. Na última década, os avanços na metodo- logia e terminologia de revisões sistemáticas exigiram a atualização da diretriz. A declaração PRISMA 2020 substitui a declaração de 2009 e inclui novas orientações para relato que refletem os avanços nos métodos para identificar, selecionar, avaliar e sintetizar estudos. A estrutura e apresentação dos itens foram modifi- cadas para facilitar a implementação. Neste artigo, apresentamos a lista de checagem PRISMA 2020 de 27 itens, uma lista de checagem expandida que detalha as recomendações para relato para cada item, a lista de checagem PRISMA 2020 para resumos e os fluxogramas revisados para novas revisões e para atualização de revisões.

[ABSTRACT]. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement, published in 2009, was designed to help systematic reviewers transparently report why the review was done, what the authors did, and what they found. Over the past decade, advances in systematic review methodology and terminology have necessitated an update to the guideline. The PRISMA 2020 statement replaces the 2009 statement and includes new reporting guidance that reflects advances in methods to identify, select, appraise, and synthesise studies. The structure and presentation of the items have been modified to facilitate imple- mentation. In this article, we present the PRISMA 2020 27-item checklist, an expanded checklist that details reporting recommendations for each item, the PRISMA 2020 abstract checklist, and the revised flow diagrams for original and updated reviews.

There is room for improvement in the use of scoping reviews in dentistry.

OBJECTIVE: To evaluate the reporting of authors' justifications for choosing the scoping review methodology in oral health. STUDY SELECTION, DATA AND SOURCE: This is a meta-research study about scoping reviews in dentistry. This study searched for reviews in PubMed and Scopus without year restrictions and restricted to English-language publications. Study selection was undertaken by two reviewers independently. Each of these reviewers extracted data from half of the included studies considering general study characteristics and scoping reviews objectives, as well as data about whether or not the authors clearly explained why they chose the scoping review framework. RESULTS: We included 184 articles. Ninety-seven of the reports did not provide a rationale as to why they chose the scoping review method (52.7%). Regarding the reported aims of the studies, 29.9% (n = 29/87) of the scoping reviews presented more than one. When comparing studies reporting the use of the PRISMA-ScR to those not reporting the PRISMA-ScR, there is no difference in the reporting of a clear explanation of why the authors used a scoping review method. CONCLUSION: There is room for improvement in how authors report their justifications for choosing the scoping review method. CLINICAL SIGNIFICANCE: Scoping reviews may be used by researchers who are unaware of this method. Educational initiatives should thus be encouraged.

Scoping review: a relevant methodological approach for knowledge synthesis in Brazil's health literature / Revisão de escopo: uma abordagem metodológica relevante para a síntese de evidências da literatura em saúde no Brasil

A methodologically robust approach to synthesize relevant knowledge in health literature is the scoping review, which is used to answer broader questions (e.g., "What is known about this concept?") and can be used to map evidence for research and practice decision-making. This paper discussed the importance of scoping reviews as a methodological approach for knowledge synthesis in Brazil's health literature. Definitions and methodological steps were discussed. We examined 45 scoping reviews that were published in Brazil's journals or available as thesis or dissertations to dis-cuss their content and methodological characteristics. Recommendations for authors were presented in order to improve the planning, executing and reporting of further scoping reviews in Brazil. This will help Brazilian researchers and health professionals to understand when and how scoping reviews can be helpful for knowledge synthesis on health topics, including for physical activity and health research area

Uma abordagem metodologicamente robusta para sintetizar a literatura relevante em saúde é a revisão de escopo, a qual é utilizada para responder questões abrangentes (por exemplo, "O que se conhece sobre um de-terminado conceito em saúde?") e pode ser utilizada para mapear evidências para a tomada de decisão prática e em pesquisa. Este artigo discutiu a importância de revisões de escopo como uma abordagem metodológica para síntese de conhecimento da literatura em saúde no Brasil. As definições e as etapas metodológicas foram discutidas. Um sumário das 45 revisões de escopo que foram publicadas em periódicos brasileiros ou como tese/dissertação foi apresentado para discutir seu conteúdo e suas características metodológicas. Recomendações para os autores foram apresentadas para melhorar o planejamento, execução e descrição de revisões de escopo a serem realizadas no Brasil. Este estudo pode ajudar pesquisadores e profissionais de saúde brasileiros a compreender quando e como revisões de escopo podem ser úteis na síntese de evidências, incluindo para o campo de pesquisas em atividade física e saúde

Systematic reviews in restorative dentistry: discussing relevant aspects.

OBJECTIVE: This article aims to discuss key aspects of systematic reviews (SR) focusing on the improvement of the conduct and reporting. METHODS: Important aspects of SRs, such as prospective registration of the review protocol, basic structure, inclusion criteria, use of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement, confidence in the results and future directions are discussed. To determine relevant aspects, a search was conducted without date limitations in PubMed (October 15th, 2017) to identify SRs written in English evaluating clinical performance of direct composite resin restoration in permanent posterior teeth or comparing direct composite resin with other material/techniques. The quality of SRs included was assessed using the Assessing the Methodological Quality of Systematic Reviews 2 tool. RESULTS: Fifteen SRs were included. The overall confidence in the results of SRs was classified as critically low. Some aspects should be highlighted: SRs of in vitro studies are an important tool in restorative dentistry, and initiatives such as the PRISMA Statement and PROSPERO should be considered a standard code of practice. CONCLUSIONS: The compliance with and awareness of the discussed aspects may be a significant feature of the improvement of SR quality in the dentistry. CLINICAL SIGNIFICANCE: Initiatives such as the PRISMA Statement and PROSPERO should be taken in account by systematic reviewers in dentistry to improve the conduct and reporting of SRs, and to make their reviews are more clinically helpful.

Systematic reviews in dentistry: Current status, epidemiological and reporting characteristics.

OBJECTIVE: This study aimed to evaluate the epidemiological and reporting characteristics of systematic reviews (SRs) in dentistry indexed within PubMed during the year 2017. METHODS: We searched for SRs in dentistry indexed within PubMed in 2017. Study selection was undertaken by two reviewers independently. Data related to epidemiological and reporting characteristics were extracted by one of three reviewers. A descriptive analysis of the data was performed. Characteristics of SRs were analyzed considering all SRs included and subgrouped by dental specialties. In addition, we explored if the reporting of 24 characteristics of treatment/therapeutic SRs was associated with the self-reported use of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement calculating the risk ratio (RR) with a 95% confidence interval for each characteristic. RESULTS: 495 articles fulfilled the eligibility criteria. The main specialty considered was Oral Surgery numbering 75 articles. Brazil presented the highest contribution with 117 SRs (23.6%). The reporting quality was variable. Items such as, use of the term "systematic review", or "meta-analysis" in the title or abstract was well reported. In contrast, the study risk of bias/quality assessment method was not reported in 40.5% of SRs. In addition, only four reporting characteristics were described more often in those SR that reported using the PRISMA Statement. CONCLUSION: A large number of SRs were published in dentistry in 2017 and the reporting and epidemiological characteristics varied among dental specialties. There is a mandatory need to improve the quality of reporting and conduct of SRs in dentistry. CLINICAL SIGNIFICANCE: Poor reporting and conduction of SRs could generate SRs with imprecise and biased results.
