The median estimated blood loss at cesarean section (CS) was significantly higher in the shorter CL group (1302\u2003mL vs 2139\u2003mL, <jats:italic>P<\/jats:italic>\u2003=\u20030.023) as was the percentage of patients with massive intraoperative hemorrhage (60.0 vs 18.3%, <jats:italic>P<\/jats:italic>\u2003=\u20030.001). In the shorter versus longer CL patients, emergent CS before 37\u2003weeks (23.3 vs 50.0%, <jats:italic>P<\/jats:italic>\u2003=\u20030.046) and the percentage of patients with placental adherence (6.7 vs 35.0%, <jats:italic>P<\/jats:italic>\u2003=\u20030.004) were both significantly more frequent in the shorter CL group. The shorter CL was a risk factor both for massive estimated blood loss (\u22652000\u2003mL) (odds ratio 6.34, 95% confidence interval 1.91\u201321.02,
