Numerical variables were expressed as the mean ± SD or median (IQR).

Categorical variables were presented as percentages. 25(OH)D, CPK and LDH levels, did not have a normal distribution, a log transformation (Ln) was applied to correct their normality distribution.

Absolute neutrophil count (ANC), absolute lymphocyte count (ALC), hemoglobin (Hb), hematocrit (HCT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood sugar (BS), blood urea nitrogen (BUN), calcium (Ca), creatinine (Cr), creatine phosphokinase (CPK), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), bicarbonate (HCO3), potassium (K), lactate dehydrogenase (LDH), magnesium (Mg), sodium (Na), platelets count (PLT), phosphorus (P), procalcitonin (PCT), partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2).
