The Stratified Win Ratio in the EMPULSE trial: combining win ratio estimates for the two strata into an overall win ratio estimate.
The primary analysis in the EMPULSE trial was the stratified win ratio, with two strata, (i) de novo heart failure patients and (ii) decompensated chronic heart failure patients. Figure 2 shows the win ratio and 95% CI in each stratum and the overall stratified win ratio and 95% CI. CI = confidence interval.
