Although life expectancy gain was not nominally statistically significant for all-cause mortality (P = .07), a significant gain in life expectancy was observed for all-cause mortality when patients were analyzed according to whether their systolic blood pressure was controlled to 140 mm Hg. For those controlled at this level at the end of the first year of follow-up, a gain of 333.2 days (95% CI, 186.1-484.8 days) was observed; for those controlled at 2 years of follow-up, 196.3 days (95% CI, 57.2-334.8 days) were gained; and those controlled at the end of the follow-up lived 206.4 days (95% CI, 52.5-355.7 days) longer. However, as Coca states, the primary finding of the study was a gain in life expectancy free from cardiovascular death.
