2.3 Data collection
Demographic characteristics of the patients at the time of admission, standing waist circumference, height, weight, body mass index (BMI), comorbidities, oxygen saturations at room air (SpO2), laboratory parameters (neutrophil, lymphocyte, neutrophil / lymphocyte ratio, lactate dehydrogenase (LDH), D-dimer, C-reactive protein (CRP), fasting blood glucose, high-density lipoprotein (HDL) cholesterol, total hospitalization periods, intensive care admission and mortality rates were recorded. Computed tomography was performed on all patients. The severity of the radiology findings was evaluated by scoring between 0-20 according to the degree of involvement of each lung lobe, as in the criteria set by Chang Y. and colleagues9. According to involvement of the disease, each of the 5 lobes was scored as:
. 0 point (0%),
. 1 point- Minimal (1-25%),
. 2 points- Mild (26-50%),
. 3 points- Moderate (51-75%)
. 4 points- Severe (76-100%).
Total radiological weight score was obtained by summing the scores of 5 lobes (0-20).
