Nomogram for predicting the deterioration and the survival of COVID-19 patients in the total cohort (n = 322). a Violin plot showing nomogram total points of different clinical types of COVID-19 patients; b Violin plot showing the correlation of nomogram total points of patients with and without deterioration; c Violin plot showing nomogram total points of alive and dead COVID-19 patients; d Kaplan-Meier survival curves based on the relative low- and high-risk patients divided by the cut-off point (P < 0.0001). Low-risk = Total point < 160; High-risk = Total point ≥160; e Time-dependent ROC curve analysis of the nomogram predicting survival of COVID-19 patients. Abbreviations: COVID-19, coronavirus disease 2019; ROC, receiver operating characteristic; AUC, area under the curve; DCA, decision curve analysis
