Main Findings
Our findings revealed a moderate level of methodological quality for
systematic reviews on the induction of labour, with no significant
changes in quality over the past two decades. We further found poor
adherence to AMSTAR criteria involving the inclusion of grey literature,
the lack of assessment of publication bias, and failure to document the
performance of a comprehensive literature search. Furthermore, the
AMSTAR score for individual systematic review assessed in our study was
not significantly related to the total number of citations to date,
impact factor of the journal in which the article appeared, or the year
of publication.
