Daytime, 24-hour, and nighttime systolic blood pressure thresholds yielding an equivalent 5-year predicted probability of the composite outcome of cardiovascular disease or all-cause mortality as clinic systolic blood pressure thresholds of 160 mmHg, 140 mmHg, 130 mmHg, and 120 mmHg.
| Clinic SBP threshold | 5-year predicted probability of CVD/all-cause mortality, % | Daytime SBP (95% CI), mmHg | 24-hour SBP (95% CI), mmHg | Nighttime SBP (95% CI), mmHg |
