  1. OR Odds ratio, CI Confidence interval, PSM Propensity score matching
  2. Data had been matched by using propensity score matching with 1:1 nearest neighbor matching. Multivariable logistic regression after PSM included entered factors variable as p < 0.05 (Epidural analgesia, Progress of Labor in previous caesarean section, Cervical score at admission, the onset of labor: Spontaneous) and using stepwise regression by AIC criteria.
