Figure 6 Mortality According to Assigned Therapy, Adjusting for Baseline Variables and Initial Response
The adjusted hazard ratio for those assigned to cardiac resynchronization therapy (CRT) was 0.672 (95% confidence interval: 0.494 to 0.914; p = 0.0113). The unadjusted hazard ratio was 0.60 (95% confidence interval: 0.47 to 0.77; p <0.0001). The curves do not differ appreciably from those derived from unadjusted data and published previously in Cleland et al. (2,3).
