Figure 1. Decreased leukocyte N6-methyladenosine (6mA) DNA level is associated with hypertension development and treatment. (A) Overall leukocyte 6mA level in people with hypertension by drug treatment successful (Good) or not (Poor), as well as in the normal individuals (Control). (B, C) Spearman correlation coefficients for leukocyte 6mA level correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP), as well as hypertension history. Data are mean ± SD and were compared by unpaired t test for A and B.
