Clinical Outcomes With BIV Versus RV Pacing: Change in QOL Over Time
The observed mean improvement in quality of life (QOL) relative to randomization for each arm at each time point. A posterior probability (PP) ≥0.95 was the pre-specified threshold for an important difference between groups. (A) Intent-to-treat analysis. (B) Accounting for crossovers The number of patients analyzed in each group is shown at the bottom. BIV = biventricular; RV = right ventricular.
