Flushing symptoms were recorded using participant's response to the Global Flushing Severity Score (GFSS), which assessed the overall severity of the flushing experience, using a scale of 0 (no symptom) to 10 (extreme). The number of days/week was derived as: 7\*(total number of days with GFSS ≥4 across Weeks 21-32 divided by the total number of days with nonmissing GFSS across the same period). The number of days/week with a GFSS ≥4 for each participant was listed in 1 of the following 6 categories: 0, \>0 to 0.5, \>0.5 to 1, \>1 to 2, \>2 to 3, and \>3 days per week.
