  1. BL, Δu and Δa respectively indicate baseline value, unadjusted change (follow-up minus baseline), and change estimates derived from mixed models, while adjusting for baseline as fixed effect and center as random effect. Baseline values are mean±s.d. Changes are crude or adjusted means with 95% confidence interval. Office minus 24-h or daytime blood pressure is a measure for the white-coat effect.
  2. Significance of the changes: *P0.05; †P0.01; ‡P0.001.
