Generalized estimating equation (GEE) models with logit link functions for repeated measure were used. Only statistically significant results are shown
*P < 0.05; **P < 0.01
†Two dependent variables include duration from onset to follow-up (days) and one of the following factors, gender, age, cigarette smoking, alcohol drinking, BMI, abroad imported patient, involvement in a cluster, duration from onset to admission (days), duration from admission to discharge (days), comorbidities, clinical intensity, any symptom, fever, pneumonia, cough, fatigue, first blood test (white blood cell count (× 109/L), leukomonocyte cell count (× 109/L))
#Duration from onset to follow-up (days) and statistical significant factors in model 1 were included in model 2. Results of all included factors are shown in the table
