Cumulative incidence of pericardial effusion (PCE) in the prospective (training) and retrospective (validation) patient groups. No significant difference was found in PCE rates between the prospective group (31.4% at 1 year, 45.4% at 2 years) and the retrospective (validation) group (28.9% at 1 year, 40.8% at 2 years) (log-rank p=0.364). Median time to PCE development was 8-9 months in both groups.
