Continuous variables are expressed as mean±s.d. Categorical variables are expressed as percentages.
The p value of the continuous variables was calculated by the Mann–Whitney U-test.
The p value of the categorical variables was calculated by Fisher's exact test. ap<0.05.
MI, myocardial infarction; BMI, body mass index; DBP, diastolic blood pressure; EH, essential hypertension; HDL, high-density lipoprotein; SBP, systolic blood pressure.
