Similar to FPG levels, it showed consistent correlation between elevated FPG and DCC (r = 0.375, P < 0.001), past DM history (r = 0.436, P < 0.001), SAA (r = 0.332, P < 0.001), CRP (r = 0.326, P = 0.001), ESR (r = 0.366, P < 0.001), imaging changes of chest CT (r = 0.251, P = 0.012), and CD8+ T cell number (r = −0.252, P = 0.012) (Table 5). The gene discussed is ESR1; the disease is diabetes mellitus.
