From: Increased RV:LV ratio on chest CT-angiogram in COVID-19 is a marker of adverse outcomes
Comparison of RV:LV ratio, PA:AO ratio, and CT severity score between control and COVID-19 groups. Box and Whisker plots comparing A the ratio of RV to LV dimensions, B the ratio of PA to AO dimensions, and C the CT severity score (CT-SS). Horizontal lines represent median, boxes first and third quartile, whiskers 95%. Groups: control normal (control group without pneumonia); control Org-PNA (control group with organizing pneumonia); COVID-AO− (COVID-19 without adverse outcomes); COVID-AO+ (COVID-19 with adverse outcomes: death, or intubation, or ICU admission). Results of post-hoc pairwise comparison shown by letters (a, b, c, d for Control Normal, Control Org-PNA, COVID-AO−, COVID-AO+, respectively); significance level (adjusted for multiple testing using Bonferroni correction): *p < 0.05, **p < 0.01, ***p < 0.001. RV right ventricle, LV left ventricle, AO aorta, PA pulmonary artery, COVID-19 novel coronavirus, Org-PNA organizing pneumonia
