Data analyses
The identified outcomes were organised into an inventory based on the
outcome measures and quality of the studies. The total number of
individual outcomes and the frequency of each reported outcome were
calculated and definitions of outcomes were analysed. The outcomes were
reviewed to reduce duplication caused by different terminologies and
similar outcomes were grouped together to create a clear and succinct
outcome inventory. A narrative synthesis was performed in addition to
the summative analysis. The outcomes were organised into broad
categories: maternal and neonatal short-term and long-term outcomes and
subsequent pregnancy outcomes. The short-term outcomes were defined as
outcomes less than one year after delivery and long-term outcomes as one
year or more.
