KDM6B and hypertensive disorder: OSA patients with low KDM6B protein expression (< 0.21 ng/μl, n = 23) had higher risk for incident cardiovascular events or hypertension in the following 3 years (p = 0.014 by Log-Rank test, Fig. 2E) than those with high KDM6B protein expression (≧0.21 ng/μl, n = 33).
