Correlation of RV:LV ratio with the probability of adverse outcomes (death, intubation, ICU admission) in COVID-19 cohort. A logistic regression (dots represent data: BROWN dots: adverse outcomes, ORANGE dots: no adverse outcomes; RV:LV ratio on the x-axis; black line represents the fit of the logistic regression, gray polygon represents 95% confidence interval). B Receiver operator curve of RV:LV ratio predicting adverse outcomes (AUC = 0.707, p = 0.002, CI 0.59–0.82, Optimal cutoff = 1.1). RV right ventricle, LV left ventricle, COVID-19 novel coronavirus
