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
<11.5	0.52	(0.39, 0.70)	<0.0001
≥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.
