aSummary measures created by taking results from individual studies, weighting by sample size and calculating summary statistic. Only presented if there is no significant heterogeneity between groups
-
bThere is evidence of significant heterogeneity between PRISON and PRISON+ groups (p = 0 · 005 for caesarean, p < 0 · 001 for inadequate prenatal care, p = 0 · 001 for preterm delivery), therefore a random effects model has been used
-
cNo summary measure possible as only one non-zero result
-
dNo summary measure possible as significant heterogeneity in results within PRISON category
