HW, BW, and TL analyses: WT vs. IL-6^−/− mice

Genotype	BW, g	HW, mg	TL, mm	HW/BW, mg/g	HW/TL, mg/mm
WT	22.8±1.48	137.2±6.53	16.6±0.13	6.0±0.30	8.3±0.44
IL-6−/−	21.6±1.39	101.6±5.77*†	17.2±0.70	4.6±0.19*†	5.9±0.52*†

Values are means ± SD; N = 5 animals per condition. Heart weight (HW), body weight (BW), tibia length (TL), and corresponding ratio for adult age-matched animals are shown. *P < 0.05, †P < 0.01, and *†P < 0.001 vs. wild-type (WT).
