In Table 2, the numbers of participants who underwent specific diagnostic tests are displayed.
The following diagnostic tests were performed: 104 24-hour blood pressures, 311 6-minute walk tests, 1,657 DXA scans, 1,352 echocardiograms, 1,385 electrocardiograms, 1,816 hand grip tests, and 586 pulmonary function tests.
