In this multi-centered, retrospective, observational study, we enrolled 523 COVID-19 cases discharged before February 20, 2020 in Henan Province, China, compared clinical data, screened for high-risk fatal factors, built a death prediction model and validated the model in 429 mild cases, six fatal cases discharged after February 16, 2020 from Henan and 14 cases from Wuhan. In this study, we collected data of 523 discharged cases of novel coronavirus infection in Henan Province, China and compared the demographics, clinical characteristics, laboratory test, imaging between the mild, severe survivors and nonsurvivors. In considering age is among leading risk factors for poor prognosis in several studies (3, 6, 7, (9) (10) (11) , we firstly constructed models by using single age, which could achieve and AUC of 0.907 (95% CI 0.831-0.983) for death and alive severe COVID-19 patients.	./cache/cord-264697-b3wd6gww.txt	./txt/cord-264697-b3wd6gww.txt
