Exercise treadmill outcomes for patients with aortic stenosis and controls
| Aortic stenosis(n = 20) | Normal controls(n = 15) | p Value* | |
|---|---|---|---|
| METS, metabolic equivalents. | |||
| Results are means (SD). | |||
| *For continuous variable, two-sample t test used and for categorical variable, χ2 test or fisher exact test where appropriate. | |||
| †Mann–Whitney U test used where variables not normally distributed. | |||
