Mortality analysis of COVID-19 patients admitted to the general ward stratified by age decade. a) Kaplan–Meier plot of patients stratified by age decade. b) Risk of 30-day mortality with age modelled as a continuous variable. The 30-day mortality probability was derived from a logistic regression. The shading represents the 95% confidence interval. c) The same method as b), but now the 30-day mortality probability is adjusted for demographics (inclusion hospital, sex and inclusion wave), age-related comorbidities (hypertension, diabetes, malignancies, immunosuppression, and chronic cardiac, neurological, respiratory and kidney disease), age-related chronic medication (antiplatelet and anticoagulant drugs), and COVID-19-related treatments both before and after sampling (corticosteroids including dexamethasone, anti-interleukin-6, imatinib, remdesivir and antibiotics).
