cesarean section | 3.27 | 1.00, 10.68 | 0.05 |
older maternal age | 1.19 | 1.01, 1.40 | 0.03 |
first live birth | 4.81 | 1.43, 16.18 | 0.01 |

- Note. Delayed lactogenesis II onset was included as dependent variable. A backward LR variable selection method was used to identify significant variables among cesarean section, maternal age, first live birth, pregnancy complications, and GA. The inclusion and removal of variables in models were based on p values of 0.05 and 0.10, respectively. Twin entered into the model through enter method due to potential clinical relevance. Cesarean section, older maternal age, first live birth, and twin entered the final model. The logistic regression model yielded statistical significance (χ2 = 14.98, df = 4, p = 0.005). The final model was checked by Hosmer-Lemeshow test for goodness-of-fit (p = 0.66)
- * p-value is based on the results of a multivariate binary logistic regression analysis. aOR = adjusted Odds Ratio. CI = Confidence Interval
