Table 2. Variables correlated with magnitude of the difference between cutaneous and tympanic temperature measurements*.

Variables	Coefficient of regression (95% confidence interval)
Tympanic temperature, °C	0.27 (0.17 to 0.37)
Age, y	−0.012 (–0.015 to –0.009)
Outdoor temperature, °C	0.04 (0.03 to 0.05)

*p<0.001 for all comparisons.
