Categorical variables are presented as count (per cent). All biomarkers are presented as median (IQR) due to non-normal distributions.
Bolded p values indicate significance at 0.05 level.
BUN, blood urea nitrogen; CRP, C reactive protein; ICU, intensive care unit; N:L, neutrophil:lymphocyte ratio; WBC, white blood cell.
