Hazard ratios of cardiovascular events by systolic blood pressure categories within the normal range.
| Parameter | SBP, mmHg | |||
|---|---|---|---|---|
| 90–99 | 100–109 | 110–119 | 120–129 | |
| Case/n | 24/1548 | 106/4599 | 265/8136 | 452/11246 |
| Incidence/1000 person-years | 1.45 | 2.15 | 3.06 | 3.80 |
| Model 1 | Ref. | 1.48 (0.95–2.30) | 2.10 (1.38–3.18)a | 2.60 (1.72–3.92)a |
| Model 2 | Ref. | 1.20 (0.77–1.88) | 1.43 (0.94–2.18) | 1.45 (0.96–2.19) |
| Model 3 | Ref. | 1.12 (0.69–1.80) | 1.21 (0.75–1.93) | 1.09 (0.67–1.77) |
| Model 4 | Ref. | 1.16 (0.71–1.89) | 1.25 (0.78–2.02) | 1.13 (0.69–1.86) |
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.
