	Female PBS	Female meth	P value	Male PBS	Male meth	P value
EF, %	97.2 (±0.36)	95.2 (±1.3)	0.11	97.8 (±0.51)	94.8 (±0.66)	0.12
FS, %	78.04 (±1.8)	69.09 (±2.1)	0.10	79.3 (±1.5)	68.0 (±1.5)	0.01*
LVID;d, mm	2.50 (±0.16)	2.73 (±0.08)	0.48	2.61 (±0.03)	2.75 (±0.10)	0.30
LVID;s, mm	0.55 (±0.03)	0.84 (±0.06)	0.07	0.47 (±0.08)	0.88 (±0.04)	0.05

PBS, phosphate‐buffered saline; EF, ejection fraction; FS, fractional shortening; LVID;d, left ventricular end‐diastolic internal diameter, LVID;s, left ventricular end‐systolic internal diameter. Data are expressed as mean ± SEM and analyzed using a two‐tailed paired t test.
