Table 1 Demographic characteristics and outcomes of Covid-19 patients admitted for treatment. The number and percentage of patients for each variable are provided in columns “survivor” and “non-survivor”. The P values are based on comparisons between “survivor” and “non-survivor” patients. BMI, body-mass index; CI, confidence interval
