  • ABP indicates ambulatory blood pressure; BP, blood pressure; Δ, change of parameter in observation period. Data are presented as mean±SD. Intergroup differences in the changes of parameters from baseline to follow-up were analyzed using an ANCOVA model adjusted for age, baseline value, and diabetes mellitus.

  • * P<0.05 was regarded significant.
