| Prematurity < 37 weeks | 0.97 | 0.611–1.523 | 0.88 |
| Postdate > 40 weeks | 2.21 | 0.244–20.01 | 0.48 |
| ASA status | 1.71 | 1.109–2.623 | 0.02 |
| Emergent procedure | 1.23 | 0.709–2.135 | 0.46 |
| Intraoperative temperature monitoring site | 1.09 | 0.976–1.206 | 0.13 |
| Intraoperative temperature change (°C)1 | 0.96 | 0.817–1.126 | 0.61 |
| Anesthesia duration (min) | 1.00 | 0.999–1.003 | 0.20 |
| Convective warmer use | 0.30 | 0.177–0.513 | <0.001 |
| Case date in 2010 or later | 0.24 | 0.157–0.378 | <0.001 |
1Intraoperative temperature change was calculated as the difference between the last intraoperative temperature value and the preoperative temperature.
