Analysis of tissue weights in controls, MI, and VNS-MI

	Controls, n = 8	MI, n = 7	VNS-MI, n = 7
Age at termination, wk	28.2 ± 1.1	30.5 ± 0.5	29.2 ± 1.9
Postoperative recovery, wk		12.8 ± 0.2	12.6 ± 0.3
Body weight (wt), g	1011 ± 56	1106 ± 52	1001 ± 94
Heart weight, % of body wt	0.65 ± 0.08	0.61 ± 0.23	0.66 ± 0.06
Wet lung weight, % of body wt	0.51 ± 0.05	0.48 ± 0.15	0.50 ± 0.05
Dry lung weight, % of body wt	0.09 ± 0.01	0.09 ± 0.02	0.10 ± 0.01

Values are means ± SD. A Shapiro-Wilk test showed normality, and no significant effect (P < 0.05) was found among groups using an ANOVA.
