We have seen a significant association between elevated CRP, PCT, IL-6, Troponin T, GGT and LDH levels and death in COVID-19 patients (CRP OR: 3.88, 95% CI: 1.08–13.97, p = 0.04; PCT OR: 3.47, 95% CI: 1.4–8.5, p < 0.01; IL-6 OR: 2.4, 95% CI: 1.18–4.99, p = 0.02; GGT OR:1.47, 95% CI: 1.06–2,04, p = 0.02; LDH OR: 1.3, 95% CI: 1.04–1.6, p = 0.02; Troponin T OR: 3.9, 95% CI: 1.19–12.81, p = 0.03). Here, IL6 is linked to COVID-19.
