Figure 5 Time to First Heart Failure Hospitalization in the First 12 Months in the CRT-OFF and CRT-ON Groups

Heart failure (HF) relatedness of hospitalizations was adjudicated by the Adverse Events Advisory Committee. The number at risk at 12 months represents the number of patients who had a randomized follow-up after 365 days and had not experienced an HF hospitalization. The number decreases at 12 months mainly because U.S. subjects finished randomized follow-up at 12 months. Abbreviations as in Figures 1 and 2.
