A bivariate correlation analysis showed that Klotho was significantly and positively related with SSI values in the sub-group of T2DM patients (r = 0.223, p < 0.01), particularly with the percentage of stenosis observed in the two major epicardial arteries: LCA (r = 0.212, p = 0.01) and RCA (r = 0.182, p = 0.04) (Table 4). The gene discussed is KL; the disease is type 2 diabetes mellitus.
