Outcomes
Primary outcome [1] 0 0
Mean Change in Frequency of Moderate to Severe Vasomotor Symptoms (MSVS) Baseline at Week 4 (2-week Period) - The primary efficacy endpoint for this study was the change from Baseline (Day 0) in the frequency of MSVS (difference between Baseline [2-week run-in period] and Week 4), where the baseline MSVS frequency was captured over 14 ± 2 day period. Moderate is defined as "sensation of heat with sweating, able to continue activity"; severe is defined as "sensation of heat with sweating, causing cessation of activity". Patients used the take-home daily diary to record MSVS information during the run-in period and treatment period and analyses were performed as specified.
Treatment group differences are estimated using least squares (LS) means and 95% confidence intervals based on the mean square error from the ANCOVA. LSMeans refer to overall adjusted mean frequency of MSVS.

Mean Change in Frequency of MSVS From Baseline at Week 4 (1-week Period) - Change from Baseline in the frequency of MSVS (difference between Baseline [period following first 7 days of 2-week run-in period] and period following first 7 days of 2-week Week 4 period), where the Baseline MSVS frequency was captured at visit 3 (Day 0), in the period following the first 7 days, as per CRF. Note: this endpoint is identical to the primary endpoint, however, instead of a 14 ± 2 day period, the period following the first 7 days was used, at Baseline and visit 3.
Treatment group differences are estimated using least squares (LS) means and 95% confidence intervals based on the mean square error from the ANCOVA. LSMeans refer to overall adjusted mean frequency of MSVS.

Secondary outcome [2] 0 0
Change From Baseline (Day 0) in the Frequency of MSVS at Week 1 and Week 2 - The frequency of MSVS per week, at each of the protocol visits, was calculated as follows, for each patient: [# of Moderate+Severe hot flushes)/(Current protocol visit date-Previous protocol visit date (days)] * 7.
The ANCOVA procedure tested the following hypotheses:
H0: µ1 = µp versus HA: µ1 ? µp, where µ1 and µp denote the mean frequency of MSVS, adjusted for Baseline MSVS values, in the treatment and placebo groups, respectively.
LSMeans refer to the overall adjusted mean frequecy of MSVS.
Timepoint [2] 0 0
1 and 2 weeks from Baseline (Day 0)
Secondary outcome [3] 0 0
Change From Baseline (Day 0) in the Severity of VMS as Recorded in the Patient Diary at Week 1, Week 2, and Week 4 - The severity of vasomotor symptoms per week at each of the protocol visits was calculated for each patient as follows: [(Sum of scores of Mild, Moderate, Severe hot flushes)/(Current protocol visit date - Previous protocol visit date (days)] * 7, where severity of vasomotor symptoms were scored as: 1 = mild, 2 = moderate and 3 = severe. Higher values represented worse severity.
LSMeans refer to the overall adjusted mean severity of VMS.
Hot Flush Classification: Mild: sensation of heat without sweating; Moderate: sensation of heat with sweating, able to continue activity; Severe: sensation of heat with sweating, causing cessation of activity.
Patients recorded the number of hot flushes (day and night) in their diaries related to the severity (mild/moderate/severe).

1, 2, and 4 weeks from Baseline (Day 0)
Secondary outcome [4] 0 0
Change From Baseline (Day 0) in Vaginal pH at Week 2 and Week 4 - The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
Normal vaginal pH is 3.8 to 4.5, slightly acidic.
The LSMeans refer to overall adjusted mean pH.
Timepoint [4] 0 0
2 and 4 weeks from Baseline (Day 0)
Secondary outcome [5] 0 0
Change From Baseline in Vaginal Maturation Index at Week 2 and Week 4 - The Vaginal Maturation Index was calculated by examining the maturation of the vaginal epithelium as adjudged by the cell types exfoliated. Parabasal cells are the least mature cells, intermediate cells display mild maturation, and superficial cells display the most maturity. The cell count is expressed as a percentage. The Vaginal Maturation Index was calculated as: 0.2*(parabasal cells, %)+0.6*(intermediate cells, %)+1.0*(superficial cells, %). This method is described in Menopause 2005;12(6):708-15.
The index serves as an objective means of evaluating hormonal secretion or response; lower values indicate more immature cells on the surface (atrophy), while higher values indicate more mature epithelium.
The LSMeans refer to overall adjusted mean percent of cells counted.

Change From Baseline in Estradiol Concentration at Weeks 2 and 4 - The LSMeans refer to overall adjusted mean estradiol concentration.

Change From Baseline in Progesterone Concentration at Week 2 and Week 4 - No repeated measures ANCOVA results are presented for change from Baseline in progesterone concentrations since the model did not converge.

Secondary outcome [8] 0 0
Mean Change in the Menopause Rating Scale Total Score From Baseline at Week 4 - MRS consists of 11 menopause symptoms. The scoring scheme is simple, i.e., the score increases point by point with increasing severity of subjectively perceived symptoms in each of the 11 items (severity 0 [no complaints] 4 scoring points [extremely severe symptoms]). The respondent provides her personal perception by checking one of 5 possible boxes of "severity" for each of the items. The composite score (total score) is the sum of the 11 item scores, which can range from 0 (no symptoms) to 44 (extremely severe symptoms). Low total scores represent less severe menopause symptoms while higher scores represent more severe symptoms.

Secondary outcome [9] 0 0
Mean Precentage Change in the Menopause Rating Scale Total Score From Baseline at Week 4 - Percentage change from Baseline at Week 4 = (Week 4 value - Day 0 value)/(Day 0 value) x 100. Note: MRS consists of 11 symptoms, where each symptom is assigned a score from 0 to 4 (0 = 'None' and 4 = 'Extremely severe').
