Model 1: adjusted for age, smoke, family history of cardiovascular disease, diabetes mellitus, previous events, low‐density lipoprotein cholesterol, estimated glomerular filtration rate, left ventricular hypertrophy, left atrial enlargement and asymptomatic left ventricular systolic dysfunction. Model 2: adjusted for the same variables plus adjustment for daytime and nighttime blood pressure for clinic blood pressure, adjustment for clinic and nighttime blood pressure for daytime blood pressure and adjustment for clinic and daytime blood pressure for nighttime blood pressure.
Abbreviations: CI, confidence interval; HR, hazard ratio; SBP, systolic blood pressure.
