Sensitivity analyses examining associations between maternal plasma concentrations of vitamins and myo-inositol at 7 weeks of gestation with postpartum blood loss after excluding cases of (A) cesarean section delivery (n = 169 excluded), or (B) large-for-gestational-age neonate at birth (n = 43 excluded). Maternal plasma concentrations of vitamins and myo-inositol were log_e-transformed and standardized while postpartum blood loss was log_e-transformed. Coefficients expressed as % change in mL blood loss per standard deviation (SD) increase in log_e nutrient concentration. Regression models were adjusted for site, preconception BMI, parity, previous cesarean section, and maternal age. Statistical significance: * p < 0.05, ** p < 0.01. Abbreviations: CI, confidence interval; LGA, large-for-gestational-age.
