Table 3 Estimates of the relative risk of cardiac failure and Excess absolute risk (EAR) (per 10,000 patient-years) of secondary cancer induction estimated with the full model. Results are shown as averages (with uncertainty expressed as 1 standard deviation). The p value is relative to the Wilcoxon signed rank paired test
