Body weight, bladder weight, and bladder weight-to-body weight ratio in wild-type, SM-specific Cre, and SM-specific Sod2^−/− mice

Groups	n	Body Wt, g	Bladder Wt, mg	Bladder Wt/Body Wt, mg/g
Wild type	12	30.1 ± 0.80	29.6 ± 1.26	0.99 ± 0.04
SM-specific Cre	7	31.3 ± 1.30	27.5 ± 1.36	0.91 ± 0.04
SM-specific Sod2−/−	18	28.3 ± 0.89	27.9 ± 1.09	0.97 ± 0.03

Data are expressed as means ± SE; n, no. of mice. SM, smooth muscle; SOD, superoxide dismutase. All mice were treated with 4-hydroxytamoxifen (OHT) at 8 wk of age and assessed 8 wk after the final OHT injection.
