Study Selection
The review was conducted using a prospective protocol and reported per
PRISMA guidelines. The study protocol was registered with PROSPERO
(CRD42020175434), where the review protocol is available. Studies were
selected for inclusion in two stages using Covidence © (2020). First, at
least two authors (AAB, KAB, MS and DG) independently reviewed the
titles and abstracts against inclusion criteria. Studies were excluded
at this stage if they did not assess mode of delivery after a history of
prior CS or were not carried out in SSA. Secondly, at least two
independent reviewers (AAB, KAB, MS and DG) reviewed the full text of
articles against inclusion criteria for final exclusion.
