In EH patients, BMD was negatively correlated with age (r = -0.787, p < 0.001), hypertension duration (r = -0.440, p < 0.001), and HbA1c (r = -0.258, p = 0.047) and positively associated with DBP (r = 0.554, p < 0.001) and SOD (r = 0.313, p = 0.015). This evidence concerns the gene SOD1 and hypertensive disorder.
