An observational study found large methodological heterogeneity in systematic reviews addressing prevalence and cumulative incidence
Abstract
Objectives The objective of this study was to assess reporting and methodological aspects of systematic reviews (SRs) on prevalence and cumulative incidence data.Study design and setting We searched PubMed up to 18 April, 2018, and drew a random sample of eligible SRs.Results The included 215 SRs were reported in 187 different journals. 58.1% were published between 2015 and 2018. Few SRs were registered with PROSPERO (5.6%). One-quarter considered articles without languages restrictions (25.1%). Regional restrictions of included studies were applied in 22.8%. A meta-analysis was carried out in 40.5% of the SRs. One hundred and six studies (49.3%) assessed risk of bias or study quality. A total of 41 different existing tools as well as 15 tools developed by the authors themselves were used. The most commonly applied tools were the Newcastle-Ottawa Scale (15.1%), STROBE (13.5%), and the Cochrane Collaboration's tool for assessing risk of bias (7.9%).Conclusion We found large heterogeneity in characteristics, reporting, and methodological aspects of SRs on prevalence and cumulative incidence data, especially when compared with other types of SRs. Newly developed or revised guidance on how to conduct and report SRs as well as instruments for critical appraisal should consider the diversity of review types.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
