Outcomes
Primary Outcomes
Change From Baseline in the Average Daily Number of Moderate to Severe Hot Flushes at Week 4
Time Frame: Baseline and Week 4
The average daily number of moderate and severe hot flushes was calculated as the sum of the number of moderate and severe hot flushes on each day divided by the number of days with data. Moderate hot flushes: sensation of heat with sweating; able to continue activity; and severe hot flushes: sensation of heat with sweating; causing cessation of activity.
Change From Baseline in the Average Daily Number of Moderate to Severe Hot Flushes at Week 12
Time Frame: Baseline and Week 12
The average daily number of moderate and severe hot flushes was calculated as the sum of the number of moderate and severe hot flushes on each day divided by the number of days with data. Moderate hot flushes: sensation of heat with sweating; able to continue activity; and severe hot flushes: sensation of heat with sweating; causing cessation of activity.
Change From Baseline in the Average Daily Severity of Hot Flushes at Week 4
Time Frame: Baseline and Week 4
Severity ranged from mild (sensation of heat without sweating); moderate (sensation of heat with sweating; able to continue activity) to severe (sensation of heat with sweating; causing cessation of activity). The average daily severity of hot flushes for each time period was calculated as (1\*Number of mild+2\*Number of moderate+3\*Number of severe)/(Total number of hot flushes). For the days with no hot flushes, the severity score was set as 0. As this was derived from the count data, there was no maximum; the minimum score was 0; the higher values showed worse outcomes.
Change From Baseline in the Average Daily Severity of Hot Flushes at Week 12
Time Frame: Baseline and Week 12
Severity ranged from mild (sensation of heat without sweating); moderate (sensation of heat with sweating; able to continue activity) to severe (sensation of heat with sweating; causing cessation of activity). The average daily severity of hot flushes for each time period was calculated as (1\*Number of mild+2\*Number of moderate+3\*Number of severe)/(Total number of hot flushes). For the days with no hot flushes, the severity score was set as 0. As this was derived from the count data, there was no maximum; the minimum score was 0; the higher values showed worse outcomes.
Number of Participants With All Adjudicated Ischemic Cardiovascular (CV) Events
Time Frame: Baseline up to Month 12
Adjudicated ischemic cardiovascular events were a composite of: a) Coronary Heart Disease (CHD)-related death; b) New Myocardial Infarction (MI) (non-procedure-related MI); c) Documented new onset of unstable angina requiring hospitalization; d) Unscheduled coronary revascularization procedures (percutaneous coronary intervention) or bypass grafting.
