Risk factors for maternal renal dysfunction using multivariate logistic regression analysis
The multivariate analysis results for the risk of maternal renal dysfunction are shown in Table 3. In multivariate analysis, maternal age, body mass index, nulliparity, gestational age at blood test, twin pregnancy, diabetes mellitus, preeclampsia, and fetal growth restriction were included as variables to calculate the odds ratio (OR) for maternal renal dysfunction. Twin pregnancy (OR 3.38), nulliparity (OR 2.31), and preeclampsia (OR 3.64) were significant risk factors for maternal renal dysfunction.
