Fig. 2: Relative risk (RR) of incident post-acute cardiovascular outcomes compared with the SARS-CoV-2-negative cohort, stratified by CHD status.

Forest plot presenting relative risk (RR) of post-acute cardiovascular outcomes comparing SARS-CoV-2-positive cohort (n = 297,920 patients) with SARS-CoV-2-negative cohort (n = 915,402 patients), stratified by congenital heart defects (CHD) status. Composite outcomes consisted of arrhythmias (atrial fibrillation, ventricular arrhythmias, atrial flutter, and premature atrial or ventricular contractions), inflammatory heart disease (pericarditis and myocarditis), other cardiac disorders (heart failure, cardiomyopathy, cardiac arrest, and cardiogenic shock), thrombotic disorders (pulmonary embolism, deep vein thrombosis, thrombophlebitis, and thromboembolism), cardiovascular-related symptoms (chest pain, palpitations, and syncope), and any cardiovascular outcome (incident occurrence of any cardiovascular outcome studied). The error bars showed the 95% confidence interval (CI) of the estimated RR.
