The presence of underlying type II diabetes was significantly associated with increased concentrations of CST (2.36 [1.19; 5.06] ng/mL vs 1.41 [0.80; 2.76], p=0.036); admission glycaemia correlated with CgA only in ICU+COVID+ patients (Spearman rho=0.284, n=49, p<0.05). The gene discussed is CGA; the disease is type 2 diabetes mellitus.
