OR, odds ratio; CI, confidence interval.
P values were calculated by multivariate logistic regression model.
#For the age group, the adjusted variables were sex, delay from symptom onset to hospital admission and with any one of comorbidity. For the sex, the adjusted variables were age, delay from symptom onset to hospital admission and with any one of comorbidity. For the delay group, the adjusted variables were age, sex and with any one of comorbidity.
*Adjusted for age, sex and delay from symptom onset to hospital admission.
