Table 1. Mean (SD) tympanic membrane temperature for the left and right ears and the difference between them, prior to and following stress.

	Time (minutes) relative to end of stress
	−120	+4.5	+33
Left ear	36.95 (0.42)	36.89 (0.46)*	36.81 (0.43)**
Right ear	36.94 (0.46)	36.89 (0.48)*	36.80 (0.45)**
Left – right difference	0.012 (0.33)	0.008 (0.34)	0.008 (0.32)

*P<.05, ^** P<.0001. P-values refer to paired two-way student t-tests of measures following stress with those at baseline (120 minutes before stress).
