Dietary factors may be associated with the occurrence of pancreatic cancer. This umbrella review aimed to review and grade the evidence for the associations between dietary factors and pancreatic cancer risk. We searched PubMed, EMBASE, Web of Science, Scopus, Cochrane Database of Systematic Reviews, and CINAHL for eli…

Systematic reviews are the apex of the evidence-based pyramid, representing the strongest form of evidence synthesizing results from multiple primary studies. In particular, a quantitative systematic review, or meta-analysis, pools results from multiple studies to help answer a respective research question. The aim of…

BACKGROUND: In systematic reviews (SRs), geographical limitations in literature searches can aid in focussing research efforts. A methodological review published in 2016 examined the approaches SR authors use to identify studies about Germany, analysing 36 SRs. OBJECTIVE: The aim of this study was to update the origin…

The use of generative AI in systematic review workflows has gained attention for enhancing study selection efficiency. However, evidence on its screening performance remains inconclusive, and direct comparisons between different generative AI models are still limited. The objective of this study is to evaluate the perf…

BACKGROUND AND OBJECTIVE: The systematic review of randomized clinical trials is crucial to assess the safety and effectiveness of intermediate procedures. The objective of this article is to present a tutorial for the planning and execution of systematic review and meta-analysis of randomized clinical trial studies.…

The aim of the present work was to identify published methodological guidance for rapid reviews (RRs) and to analyze the recommendations with regard to time-saving measures. A literature search was performed in PubMed and EMBASE in November 2020. In addition, a search based on Google Scholar and websites of governmenta…

Systematic reviews with meta-analysis of studies on diagnostic tests or prognostic factors are research tools that are still being developed. The objective of the present paper is to describe the methodology of systematic review and meta-analysis of this type of studies, step by step. A literature review on the subject…

At the top of the evidence-based pyramid, systematic reviews stand out as the most powerful, synthesizing findings from numerous primary studies. Specifically, a quantitative systematic review, known as a meta-analysis, combines results from various studies to address a specific research question. This review serves as…

BACKGROUND: There has been increased interest in the role of cannabis for treating medical conditions. The availability of different cannabis-based products can make the side effects of exposure unpredictable. We sought to conduct a scoping review of systematic reviews assessing benefits and harms of cannabis-based med…

It is widely recognised that findings from experimental studies should be replicated before their conclusions are accepted as definitive. In many research areas, synthesis of results from multiple studies is carried out via systematic review and meta-analysis. Some fields are also moving away from null hypothesis signi…

BACKGROUND: The scoping review has become an increasingly popular approach for synthesizing research evidence. It is a relatively new approach for which a universal study definition or definitive procedure has not been established. The purpose of this scoping review was to provide an overview of scoping reviews in the…

Framework synthesis is one systematic review method employed to address health care practice and policy. Adapted from framework analysis methods, it has been used increasingly, using both qualitative and mixed-method systematic review methods. This article demonstrates a spectrum of approaches to framework synthesis th…

OBJECTIVE: This scoping review of reviews aims to describe the current landscape of measures of emotional well-being (EWB). METHODS: Following established practices for scoping reviews, we searched the PsycInfo, ERIC, Scopus and PubMed databases in June and July 2021 for reviews of measures of EWB that described their…

As part of National Association of Hispanic Nurses' Strategic Plan, our organization focuses on the development of scholarship in our members. Scholarship is what moves nursing science forward and includes not only research but also teaching/education and clinical practice. Part of scholarship is identifying what is in…

INTRODUCTION: Given the diversity of the scope for inquiry and methodologies used in nursing research, the synthesis of primary research may not be as straightforward as conducting a meta-analysis or systematic review on clinical trials. Scoping reviews offer an option to nursing academics for inquiries involving a ran…

Review articles are an important source of clinical information for family physicians. However, the volume of available reviews is vast and their scientific quality varies enormously. Family physicians must be able to identify trustworthy reviews quickly. This article outlines practical and flexible guidelines for crit…

Publishing systematic review protocols is a fundamental part of systematic reviews to ensure transparency and reproducibility. In this scoping review, we aimed to evaluate reporting of Cochrane systematic review protocols with network meta-analyses (NMA). We searched all Cochrane NMA protocols published in 2018 and 201…

BACKGROUND: The social domain of frailty is often poorly defined or missing from measures of frailty. The literature is still inconclusive on the nature and scope of social frailty, although studies indicate that it has a substantial impact on disability and mortality outcomes. AIMS: This Umbrella Review aimed to synt…

OBJECTIVES: Public and patient engagement (PPE) is increasingly recognized in policy statements as essential to achieving transformation towards patient-centred, value-based, integrated care. Despite extensive research over two decades, important gaps and questions remain around how the efforts invested in engagement d…

BACKGROUND: The exponential growth of the biomedical literature necessitates investigating strategies to reduce systematic reviewer burden while maintaining the high standards of systematic review validity and comprehensiveness. METHODS: We compared the traditional systematic review screening process with (1) a review…
