Table 4 The results of 2-piecewise linear regression model of association between level of maternal preoperative hemoglobin and risk of massive intraoperative hemorrhage.
| Inflection point of PreHb (per g/dL change) | Effect size (OR) | 95% CI | P value |
|---|---|---|---|
| 0.52 | (0.39, 0.70) | ||
| ≥11.5 | 1.06 | (0.64, 1.75) | 0.7602 |
| Adjusted potential confounders: age, region, gestational age at delivery, gravidity, parity, vaginal delivery, uterine anomalies, assistant reproduction technology, placental location, type of placenta previa, hemorrhage during pregnancy, and grade of placenta accreta spectrum disorders. | |||
