The risk factors for fatal outcome of the COVID-19 patients estimated by a logistic regression based on a case-control design (a) and competing risk model for fatal outcome of COVID-19 patients over time (b) in China to 29 March 2020. The case group included the fatal patients outside Hubei province and from six hospitals in Wuhan. The control group included the survival patients from the six hospitals and a part outside Hubei province. The proportion of patients that survived and died of COVID-19 for age and clinical intervals is shown in the left panel. In the center and right panels, the dots are odds ratios (ORs) or SHR and the error bars are 95% confidence intervals. For the model with all the patients, the OR and SHR are shown in the center column for all patients (red) and in the right panel for the patients in Wuhan (pink) and outside Hubei Province (light blue), estimated via a multivariate logistic regression model and a multivariate competing risk model. The dotted line in the center and right panels indicates an OR of 1. SHR, sub-distribution hazard ratio
