CRP and Abnormal renal physiology: Compared to those who had normal renal function at baseline, patients with renal dysfunction at baseline had higher median values of age (62 vs. 41 years), BMI (24.4 vs. 22.8 kg/m2), chest computed tomography (CT) score (14 vs. 9.5), C-reactive protein (CRP) (17.07 vs. 7.04 mg/L), urea (5.09 vs. 3.71 mmol/L), creatinine (89 vs. 59 μmol/L), and erythrocyte sedimentation rate (ESR) (42 vs. 25 mm/h), while they had lower median values of the PaO2/FiO2 ratio (P/F ratio) (368.57 vs. 432.38), platelet count (152 vs. 192 × 109/L), and lymphocyte (1.13 vs. 1.36 × 109/L) (all p < 0.05).
