In the second adjustment model, type 2 diabetes was not associated with death after adjusting for additional clinical and laboratory variables (low oxygen saturation, high urea, high CRP, high neutrophil count, liver function tests (AST, ALT, GGT), eGFR and low platelet count) (OR 1.08; 95% CI 0.71–1.66). Here, GPT is linked to type 2 diabetes mellitus.
