Independent predictors of preterm delivery in multiple logistic regression analysis (n=923)
| Variable | OR (95% CI) | p Value |
|---|---|---|
| Maternal haemoglobin after delivery (g/l) | 0.97 (0.96–0.99) | <0.001 |
| Smoking | 2.44 (1.18–5.05) | 0.024 |
| Gravidity | 0.82 (0.68–0.99) | 0.026 |
| Chloroquine | 0.41 (0.19–0.92) | 0.041 |
Odds ratios represent the risk of preterm delivery for a 10 g/l increase in maternal haemoglobin or the presence of a categorical variable. BMI was available for 466 women only and was not included in this model (see text).
