A) Model carried out only with clinical parameters and routine laboratory parameters, Nagelkerke R2, 0.324. Hosmer-Lemeshow χ2, 4.62, df 8; p = 0.796. B) Model carried out with clinical parameters, routine laboratory parameters and pro-inflammatory cytokines. Nagelkerke R2, 0.402. Hosmer-Lemeshow χ2 9.58, p = 0.296. B, beta coefficient. SE, standard error; OR, odds ratio; SpO2, peripheral capillary oxygen saturation; LDH, lactate dehydrogenase; NLR, neutrophil/lymphocyte ratio; IP-10, interferon γ-induced protein 10; IL-1β, interleukine-1β.
