 Comparison of insulin parameters of 75g-oGTT in patients categorised according to the number of significantly stenosed coronary arteries

0-VD1-VD⩾2-VD
Data are mean (SD).
*p<0.05 v 0-VD; †p<0.05 v ⩾2-VD and MI (−) by Kruskal-Wallis test followed by Mann-Whitney U test with Bonferroni correction.
AUCins, area under the insulin curve in 75g-oGTT; HOMA-IR, insulin resistance estimated by homeostasis model assessment; IRI, plasma insulin concentrations before (0) and after (30, 30 minutes; 60, 60 minutes; 120, 120 minutes) the ingestion of a 75 g oral glucose challenge.
