Covariate-adjusted mean office–home morning SBP differences according to frailty and antihypertensive treatment status. Values are presented as the adjusted mean ± standard error. Differences in SBP were calculated by subtracting the home morning SBP from the office SBP. Group differences were assessed by an analysis of covariance adjusted for age, sex, regular drinking, body mass index, office SBP, and measurement season. Post-hoc analysis was performed using Bonferroni’s test. SBP Systolic blood pressure
