Table 1.
Baseline characteristics of trial participants overall and according to randomized assignment
| Overall, N = 975 | Usual care, N = 341 | Weight loss, N = 147 | Sodium reduction, N = 340 | Combination, N = 147 | |
|---|---|---|---|---|---|
| Age, mean (SD), y | 65.8 (4.6) | 65.9 (4.5) | 65.8 (4.7) | 65.8 (4.6) | 65.7 (4.8) |
| Women, % | 47.8 | 46.9 | 51.0 | 49.1 | 43.5 |
| Black race, % | 23.6 | 24.0 | 26.5 | 21.8 | 23.8 |
| Systolic blood pressure, mm Hg | 128.2 (9.3) | 127.6 (9.4) | 129.1 (9.1) | 128.3 (9.4) | 128.4 (9.4) |
| Diastolic blood pressure, mm Hg | 71.4 (7.3) | 71.3 (7.2) | 71.5 (7.8) | 71.3 (7.4) | 71.5 (6.8) |
| Normal blood pressurea, % | 17.1 | 18.2 | 15.0 | 17.4 | 16.3 |
| Obesity, % | 60.0 | 43.1 | 100.0 | 42.4 | 100.0 |
| Diabetes, % | 4.2 | 3.6 | 4.1 | 5.4 | 2.7 |
| Current smoking, % | 5.3 | 5.9 | 2.7 | 5.3 | 6.8 |
aSystolic blood pressure <120 mm Hg and diastolic blood pressure <80 mm Hg. Only 963 participants provided baseline diabetes information; thus, the denominators for diabetes across randomized assignments were 334 for usual care, 146 for weight loss, 336 for sodium reduction, and 147 for the combination of weight loss and sodium reduction.
