Effects of Manipulations on Measured Temperatures of 8 Elderly Subjects Without Sleep Complaints and 8 Elderly Subjects With Insomnia

	T_re	T_prox	T_dist
Elderly without sleep complaints
Overall mean	36.86 ± 0.09	35.03 ± 0.01	35.00 ± 0.15
CBT	0.20 ± 0.03^a		0.41 ± 0.06^a
PST		0.71 ± 0.04 ^a	0.29 ± 0.06^a
DST			0.82 ± 0.06^a
Elderly Insomniacs
Overall mean	36.80 ± 0.07	35.00 ± 0.09	35.18 ± 0.11
CBT	0.16 ± 0.02^a		0.42 ± 0.05^a
PST		0.73 ± 0.04^a	0.27 ± 0.05^a
DST		0.09 ± 0.04^b	0.72 ± 0.05

Estimates of the effects, i.e. mean ± SEM difference of temperature (°C) in the warm relative to cool manipulation conditions, for core body temperature (T_re), proximal skin temperature (T_prox), and distal skin temperature (T_dist) before lights off. CBT, PST, DST manipulation were included in the model as dichotomous variables, with cool and warm coded as 0 and 1. The full regression model was as follows: T_ijk = ß_0ijk + ß₁*Hour_ijk + ß₂*Hou²_ijk + ß₃*√Hour_ijk+ ß₄*CBT_ijk + ß₅*PST_ijk + ß₆*DST_ijk.Subscripts indicate the i^th observation on day j for subject k. Hour = Time of day, not shown.
