The relative risk (RR) of death was significantly higher in patients with age ≥ 60 years (RR = 1.555 (95% CI: 1.283, 1.884)), concomitant hypertension (RR = 1.284 (95% CI: 1.070, 1.540)), preexisting chronic kidney disease (RR = 2.081 (95% CI: 1.147, 3.773)), IL-6 ≥ 100 pg/ml (RR = 1.515 (95% CI: 1.172, 1.956)), D-dimer ≥ 1000 ng/ml (RR = 2.134 (95% CI: 1.542, 2.954)) and CT severity index ≥ 18 (RR = 2.491 (95% CI: 1.882, 3.299)). This evidence concerns the gene IL6 and chronic kidney disease.
