OR, odds ratio; 95% CI, 95% confidence interval. Model 1 was unadjusted; Model 2 was adjusted for sex (males, females) and age (in years, continuous) at the last BP measurement and education; and Model 3 was additionally controlled for mean values of SBP and DBP (mmHg, continuous) in childhood, based on Model 2.
