Table 2. Baseline Laboratory Characteristics of Participants According to Gender.
Values are either in mean +/- SD or n(%) or median (IQR)
*Median (IQR) for not symmetrically distributed quantitative variables
**Mean ± SD for quantitative variable
CRP: C-reactive protein; IQR: interquartile range; NLR: neutrophil to lymphocyte ratio; PaO2/FiO2: partial pressure of oxygen/fraction of inspired oxygen; SD: standard deviation; TLC: total leukocyte count
