  1. Data are mean±SD by ANOVA. NT, normotensive control subjects; T1D, patients with type 1 diabetes; T2D, patients with type 2 diabetes; HT, patients with essential hypertension; BMI, body mass index; FPG, fasting plasma glucose; SBP, systolic blood pressure; DBP, diastolic blood pressure; MESOR, midline-estimating statistic of rhythm; PP, pulse pressure; AASI, ambulatory arterial stiffness index. P value between the 4 groups; * P < 0.05 vs controls; ° P < 0.05 vs T1D; # P < 0.05 vs T2D.
