Fig. 6. Correlations of residual serum leptin with (A) residual gross energy intake
(r2=0.598, F1,30=44.7,
P<0.001), (B) residual resting metabolic rate (RMR)
(r2=0.384, F1,30=18.7,
P=0.001) and (C) uncoupling protein 1 (UCP1) content (positive only
in the warm: r2=0.543, F1,14=16.6,
P=0.001; but not in the cold: r2=0.075,
F1,14=0.299, P>0.05) in non-reproductive (NR)
and lactating females exposed to 23°C (warm) and 5°C (cold).
