Effect of CH treatment on operative time (a) and total intraoperative hemorrhage volume (b). There was no significant difference in the operative time between the non-CH and the CH group (median 112 min [95% CI 108–117] vs. 103 min [95% CI 95–112], P = 0.062) (a). The volume of intraoperative bleeding was significantly lower in the CH than in the non-CH group (median 17.3 mL [95% CI 6.9–27.7] vs. 29.7 mL [95% CI 24.0–35.5], P = 0.040) (b).
