The categorical variables are presented as counts and percentages. The continuous variables are presented as median and IQR. The Chi-square test was used for categorical variables and the Mann–Whitney U test for continuous variables. p < 0.05 was considered significant. OR—odds ratio; CI—confidence interval; IQR—interquartile range; Y—yes, N—no; CAD—coronary artery disease; CKD—chronic kidney disease; COPD—chronic obstructive pulmonary disease; SpO2—saturation of peripheral oxygen; TLC—total leucocyte count; ANC/ALC—absolute neutrophil count/absolute lymphocyte count.
