• PRISMA-S |
| Aim | To assess the reproducibility of search strategies (PRISMA-S) in a random sample of 100 biomedical systematic reviews indexed in MEDLINE in November 2021. |
| Level of Investigation | Descriptive |
| Summary of Findings | From a random sample of 100 biomedical systematic reviews indexed in MEDLINE in November 2021, the reproducibility of search strategies (PRISMA-S). The included 100 systematic reviews contained 453 database searches. Of those, complete database information, including naming the database and platform (PRISMA-S item 1), was available for 47.2% (214/453) (Table 1). Only 4.9% (22/453) database searches clearly reported all six PRISMA-S items. Least commonly reported were item 9, limits and restrictions, and item 13, dates of searches. Limits and restrictions were fully reported for 22.1% (100/453) of database searches, and the exact date of the search was provided for 22.7% (103/453) database searches. |
