Data are in n (%) and risk ratio RR (95% CI) and adjusted risk ratio aRR (95% CI). CS = caesarean section. The table includes singleton births by women from rural areas.
Univariate analyses using Pearson's chi-squared tests.
Multivariate analyses using generalised linear models for binary outcomes with the log link to adjust for mothers' age, parity, previous CS and year of current birth.
Proportion of previous CS could not be adjusted for due to the number who had vaginal birth combined with previous CS was less than 1%.
Planned CS was excluded from reference group.
