Table 4. Rewarming outcomes of patients in the 3 groups.
| Parameter | Group C (n=44) | Group F1 (n=44) | Group F2 (n=44) | P value |
|---|---|---|---|---|
| Mean rewarming timea (min), mean (SD) | 37.39 (16.58) | 35.11 (15.64) | 33.30 (13.81) | .460 |
| Decrease temperature below 36 °C after achieving normothermia, n (%) | 7 (15.91) | 11 (25) | 1 (2.27) | .009 |
| Warming more than 1 h, n (%) | 10 (22.73) | 7 (15.91) | 1 (2.27) | .017 |

For the mean rewarming time, no significant differences were observed among groups; the mean differences (95% CI) compared to group C were −2.28 (−9.03 to 4.47) for group F1 and −4.09 (−10.46 to 2.28) for group F2. However, a statistically significant difference was observed in the proportion of patients with temperature decrease below 36 °C (P=.009; significant pairwise differences were observed for group F1 vs group F2 [relative risk (RR)=11.00; 95% CI 1.48‐81.61]) and those requiring warming for more than 1 h (P=.017; significant pairwise differences were observed for group C vs group F2 [RR=10.00; 95% CI 1.34‐74.84]).
