Figure 1. Percent of Participants Reporting Clinically Significant Improvement in Hot Flashes From Baseline by Intervention Arm.
Data points are the percent improved at each time point in the placebo group (N=247) and in the active drug group (N=297). Not all participants had data at all weeks.
Repeated measures logistic regression modeled 50% reduction in HF from baseline (yes/no) as a function of intervention (active drug vs. placebo), week (1-8) as a continuous variable and intervention*week, adjusted for study and clinic center.
Main effects of intervention and week, P<0.001 for each; interaction between intervention and week, P=0.88.
