| Level of Investigation | Descriptive |
| Summary of Findings | from 171 included systematic reviews identified through PubMed with no restriction on the language of publication date. Of the 171 SRs evaluated using PRISMA and GRADE, approximately one fifth presented evidence with a high level of certainty. Grey literature was searched in 54 SRs (46.1%) and 55% stipulated English-language studies only. The number of databases searched ranged from 1 to 7 and the number was not reported in 4 SRs. The authors found that the primary research question was not completely answered large number of SRs, due to 1) lack of well-designed and well-controlled studies 2) the publication of SRs with only moderate certainty of evidence, and 3) the lack of a universal protocol. The findings were only discussed generally, and the primary outcome was not adequately addressed in 5 SRs (2.9%). Only 45.61% of SRs reported evidence that can assist in clinical decision-making, and only 22.80% presented evidence with a high level of certainty according to the GRADE. Duplicate publications of very similar topics already covered in the literature were found in 48 SRs and fewer than 10 studies were examined in 71 SRs (41.52%). |
