Effect of social isolation versus pairing on body weight, heart weight, and total cholesterol.

	Absolute Body Weight (g)	Absolute Heart Weight (g)	Heart Weight-Body Weight	Total Cholesterol (mg/dl)
Paired	32.3 ± 1.2	0.14 ± 0.007	0.0043 ± 0.0002	44.7 ± 9.5
Isolated	34.3 ± 1.0	0.17 ± 0.005*	0.0050 ± 0.0002*	46.3 ± 7.4

Note: values are shown as mean ± SEM for n=16 paired and n=18 isolated animals (except for cholesterol, which includes a subgroup of n=8 paired and n=8 isolated animals).

^*P < 0.05 vs. respective paired value.
