Eligibility Criteria
Search results were uploaded into the Covidence software for systematic
reviews (Veritas Health Innovation Ltd). Articles with duplicate titles
were removed and a two-stage independent screening process was used to
select studies for inclusion. Pilots were run for the initial stage of
screening until review authors (N.W. and M.M.) reached a kappa agreement
value of 0.8. Subesequently, reviewers independently screened titles and
abstracts. Articles deemed eligible at this stage moved onto full-text
screening. Discrepancies that arose during both stages of screening were
resolved by joint-discussion among the authorship team until concensus
was achieved. The inclusion criteria involved: (1) self-identified as a
systematic review in the title or abstract; (2) systematic review must
examine primary literature; (3) systematic review must investigate the
safety, efficacy, and/or effectiveness of any method of induction of
labour. The exclusion criteria involved: (1) non-intervention systematic
reviews (e.g. diagnostic or screening tools); (2) non-english
literature; (3) non-human based studies; (4) systematic reviews of
systematic reviews; (5) conference abstracts and outdated reviews (when
an updated version was avaialble and included); (6) reviews intended to
examine the current state of literature, where participant outcomes were
not the outcome of interest; and (7) conference abstracts and
meta-analyses that did not incorporate a systematic review.
