Validation of a Prediction Model for Intraoperative Hypothermia in Patients Receiving General Anesthesia

Table 3

Accuracy of risk score cutoffs for predicting intraoperative hypothermia in all 227 participants undergoing general anesthesia.

Variable (95% CI)	Risk score cutoff
	70	90
Sensitivity (%)	85.9 (79.0–92.7)	42.4 (32.7–52.2)
Specificity (%)	36.7 (28.4–45.1)	80.5 (73.6–87.3)
LR+	1.36 (1.16–1.58)	2.17 (1.43–3.31)
LR-	0.39 (0.23–0.66)	0.72 (0.59–0.86)
PPV (%)	51.2 (43.6–58.8)	62.7 (51.1–74.3)
NPV (%)	77.0 (66.5–87.6)	64.4 (57.0–71.8)

CI, confidence interval; LR-, negative likelihood ratio; LR+, positive likelihood ratio; NPV, negative predictive value; PPV, positive predictive value.
