*Comparisons were done between deaths and survivors. X2 was used to compare categorical variables. Mann-Whitney U test was used to compare continuous variables.
BMI, body mass index; CAD, coronary artery disease; CKD, chronic kidney disease; COPD, chronic obstructive pulmonary disease; CPAP, continuous positive airway pressure; CPK, creatine phosphokinase; IMV, invasive mechanical ventilation; SpO2, oxygen saturation; WCC, white cell count.
