Change in predictors of 30-day mortality among hospitalised US veterans with COVID-19 between 20 March and 19 April 2020 and between 20 August and 19 September 2020. The yellow dots represent the prevalence of predictors in 20 March–19 April 2020, while the green dots represent the prevalence of predictors in 20 August–19 September 2020. In the Δ column, the blue text indicates that the change of predictor leads to decrease in mortality rates, while the red text indicates the change of predictor leads to decrease in mortality rates.
