    Outcomes

    Primary Outcome Measures

    Number Participants With Days Per Week With Global Flushing Severity Score (GFSS) ≥4 Partitioned Into 6 Categories During the Postwithdrawal Period
    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.

    Secondary Outcome Measures

    Number of Participants With Maximum GFSS ≥4 During the Post-withdrawal Period
    Flushing symptoms were recorded using participant's response to the Global Flushing Severity Score (GFSS), which assesses the overall severity of the flushing experience (including redness, warmth, tingling, or itching) using a scale with response categories of None, Mild, Moderate, Severe, and Extreme. The categories were supplemented with numbers 0 to 10 to allow for greater precision within each category (None=0, Mild=1-3, Moderate=4-6, Severe=7-9, Extreme=10). The daily response was recorded in the morning, and reflected the symptoms experienced during the previous 24 hours.
