Systematic reviews on selected nutrition interventions: descriptive assessment of conduct and methodological challengesby Rehana A Salam
Rigorous and transparent systematic reviews are recognized internationally as a credible source for evidence of effectiveness. However, in the field of nutrition, despite attempts at developing consensus on actions and interventions to reduce undernutrition and micronutrient deficiencies, there is lack of coordination among various groups. Each of these methodological choices influences the findings of the reviews, and lack of standardization across these domains increases the complexity for users of systematic reviews in interpreting results. There is a need to develop a consensus on methodologies for nutrition reviews, criteria for assessing the evidence and possibly facilitating development and collation of the evidence in the subject area.
Preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) 2015 statementby Moher et al
The authors in this paper describe the development of a reporting guideline, the Preferred Reporting Items for Systematic reviews and Meta-Analyses for Protocols 2015 (PRISMA-P 2015). PRISMA-P consists of a 17-item checklist intended to facilitate the preparation and reporting of a robust protocol for the systematic review. Funders and those commissioning reviews might consider mandating the use of the checklist to facilitate the submission of relevant protocol information in funding applications. Similarly, peer reviewers and editors can use the guidance to gauge the completeness and transparency of a systematic review protocol submitted for publication in a journal or other medium.
The methodology of systematic reviews—although laid out three or more decades ago—is continuously and rapidly updated by scientists specializing in research synthesis. Now, Systematic Reviews is publishing a series of articles including methods and examples of accelerating approaches to conducting literature reviews.
