p: analyzed by multinomial logistic regression analyses and considered significant at < 0.05 (2-tailed). The reference category is normal-term delivery. b: parameter considered redundant and set to zero. B: regression coefficient. ExpB: exponentiation of B, which is the same as AOR: adjusted odds ratio. 95% CI: 95% confidence interval.
