TABLE 2.

Intra-class correlation coefficients for agreement between esophageal temperatures versus rectal and temporal artery temperatures during operative procedures

Time*	Esophageal versus rectal probe	Esophageal versus rectal thermometer†	Esophageal versus temporal artery
10–30 min (n=52)	0.77		0.83
95% CI	0.63 to 0.86		0.72 to 0.90
31–60 min (n=10)	0.93		0.88
95% CI	0.79 to 0.98		0.60 to 0.97
61–120 min (n=39)	0.91		0.82
95% CI	0.83 to 0.95		0.62 to 0.91
Final‡ (n=80)	0.91	0.95	0.88
95% CI	0.86 to 0.94	0.91 to 0.97	0.82 to 0.92

^*Postintubation;

^†n=40 for rectal thermometer measurements;

^‡Refers to measurement at the end of the procedure, time depends on length of procedure (65±21 min, range 25 min to 120 min)
