Linear regression analyses were performed to examine the association between DST variables and BAT ¹⁸F-fluorodeoxyglucose uptake. Model 1 was adjusted for sex (N = 77) and model 2 for sex and the mean personal environmental temperature over the L10 period (personal-ET_L10, n = 76). The nonstandardized B coefficient, adjusted R², and p value are provided. Significant values are shown in bold (p ≤ 0.05). IS = interday stability; IV = intraday variability; L10 = mean of the 10 consecutive hours with the lowest values and when they occurred (TL10); M5 = mean of the 5 consecutive hours with the highest values and when they occurred (TM5); RA = relative amplitude.
