From: Vitamin D and 1-hour post-load plasma glucose in hypertensive patients
Vitamin D status according to different groups of glucose tolerance. In the figure, the vitamin D status, according to different groups of glucose tolerance, is represented. Of interest, vitamin D sufficiency significantly decreases from normal glucose tolerant subjects with 1-hour post-load plasma glucose <155 mg/dl (NGT < 155) to NGT ≥ 155 subjects, impaired glucose tolerant (IGT) subjects and type-2 diabetic (T2D) patients (P < 0.0001). On the contrary the prevalence of vitamin D deficiency significantly increases from the first to the fourth group (P < 0.0001).
