Abstract

Objectives To investigate the meta-epidemiology and reporting characteristics of mapping reviews. Study design and setting We conducted a scoping review of a sample of recent mapping reviews (2022-2023) by searching nine electronic databases and eleven institutional websites up to January 2024. A 28-item reporting checklist, developed by our team and based on existing guidance and methodological studies of mapping reviews, was employed to assess reporting characteristics. The median (interquartile range [IQR]) was calculated based on the number of studies that reported each specified reporting item. Results A total of 451 mapping reviews were included, with 197 published in 2022 and 254 in 2023. The USA published the most studies (80, 17.74%) and the University of London being the most active institution (23, 5.10%). Barbosa JLV from Universidade do Vale do Rio dos Sinos authored the highest number of studies, with significant collaborations primarily between Chinese and Canadian teams. The studies spanned 11 fields within health and social sciences, Environmental Evidence and Campbell Systematic Reviews published the most studies. A random sample of 200 studies was further assessed for reporting characteristics, where items such as title, author, abstract, background, conclusions, acknowledgments, contributions of authors, declarations of interest, and sources of support were reported by over 50% of the studies. Median number of studies reporting items related to methods, re…

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.
