Data are presented as means (SEs) or frequencies (%) as appropriate. Some data were missing for cardiometabolic variables.
Group 1: participants with elevated BP diagnosed by both definitions; Group 2: participants with elevated BP detected by the traditional definition but normal BP reclassified by the recommended definition; Group 3: participants with normal BP identified by both definitions. There are 0 participants with normal BP detected by the traditional definition but elevated BP reclassified by the recommended definition.
Abbreviations: BMI, body mass index; HDL, high‐density lipoprotein; LDL, low‐density lipoprotein.
Comparison of demographic characteristics between groups was performed using univariate linear regression models or chi‐square test.
Compared with adjusted alpha levels (0.05/2) due to multiple comparisons.
Comparison of cardiometabolic characteristics between groups (coded as the dummy variables) was performed using multiple linear regressions after adjusted for sex, age, and height.
