aCompared to spontaneous vaginal delivery
bProlonged labor is defined as prolonged duration of delivery at any stage (stage 1, stage 2, or combined)
*Odds ratio of less than 1 and p<0.05 indicate that C-section is a significant protective factor against RH #Odds ratio greater than 1 and p < 0.05 indicate that prolonged labor is a significant risk factor for RH
