Table 3.
Hazard ratios of cardiovascular events stratified by baseline systolic blood pressure categories in the normal range, after further excluding participants who had a DBP ≥ 80 mmHg.
| Characteristic | SBP, mmHg | |||
|---|---|---|---|---|
| 90–99 | 100–109 | 110–119 | 120–129 | |
| Case/N | 24/1545 | 96/4189 | 161/5158 | 108/2740 |
| Incidence/1000 person-years | 1.46 | 2.14 | 2.94 | 3.76 |
| Model 1 | Ref. | 1.47 (0.94–2.30) | 2.01 (1.31–3.09)a | 2.57 (1.65–4.00)a |
| Model 2 | Ref. | 1.23 (0.78–1.92) | 1.35 (0.88–2.07) | 1.19 (0.76–1.87) |
| Model 3 | Ref. | 1.22 (0.75–1.99) | 1.28 (0.78–2.11) | 1.06 (0.62–1.79) |
| Model 4 | Ref. | 1.25 (0.76–2.08) | 1.32 (0.79–2.22) | 1.10 (0.64–1.89) |
Model 1: unadjusted. Model 2: adjusted for age and sex (male/female). Model 3: adjusted for age, sex (male/female), alcohol consumption status (never and past, current, ≥1 time/day), ever smoking (yes/no), education level (elementary school, high school or above), exercise (none, occasionally or frequently, ≥1 times/week), prediabetes (yes/no), family history of cardiovascular diseases (yes/no), diastolic blood pressure, body mass index, serum concentrations of total cholesterol, high-density lipoprotein cholesterol, glucose, uric acid and C-reactive protein, and estimated glomerular filtration rate. Model 4 was a competing risk model of death which adjusted for all the confounders in model 3. Compared with reference group.
