   Participants recorded daily in their electronic diary (eDiary) the frequency and severity of hot flushes during the treatment period. The baseline assessment for hot flushes was calculated using the last 7 days (not necessarily consecutive days) with an available data in the evening and/or the morning of the baseline diary completion period. A diary day was comprised of the evening entry of this day and the morning entry of the following day, in that order. Mean daily frequency = Sum of number of hot flushes filled in the diary during the last 7 diary days (with at least one available data in the evening and/or morning) divided by 7. Moderate: Sensation of heat with sweating, but able to continue activity. Severe: Sensation of heat with sweating, causing cessation (stopping) of activity.

    The HFRDIS is a 10-item, self-report questionnaire assessing the impact of hot flushes on a woman's life during the past week. For each of the 10 items, participants rated how much hot flushes had interfered with that aspect of their life on a scale of 0 (not at all) to 10 (very much so). The total score was calculated by adding the scores for all 10 items. Higher scores indicated greater interference.
12. Change From Baseline in the Menopause-specific Quality-of-Life Questionnaire Intervention Version (MenQoL-I) Scores at Weeks 4, 8, 12 and 16 [ Time Frame: From baseline to Weeks 4, 8, 12 and 16; ]

    The MenQoL-I is a validated questionnaire used to measure condition-specific quality of life in menopausal women. It is composed of 32 items across four domains (physical, vasomotor, psychosocial and sexual). For each item, participants recorded whether they had experienced the problem in the past month, and if so, they rated how bothered they were by the problem on a scale of 0 (not at all bothered) to 6 (extremely bothered). The item scores were converted to a score ranging from 1 to 8.

    Domain scores are calculated by averaging the converted individual item scores (range 1-8) related to the respective domain. (Domains: Vasomotor - items 1 to 3, Psychosocial - items 4 to 10, Physical- items 11- to 26, Sexual - items 27 to 29). For a MENQOL total score the aggregated mean of the mean domain scores is calculated. Higher scores indicate greater bother.

    Urine for urinalysis was collected and sent to the central laboratory for analysis. Clinical relevance was judged by the investigator. Assessment was done using standard laboratory practice.

    For evaluation of the chemical properties of the urine sample test strips were used which have test pads of chemicals that change color when they come in contact with reagents. The degree of color change correlates with the amount of reagent present. Each color block represents a range of values. Range and direction of scores for reagents nitrite and urobilinogen: negative = normal; positive = abnormal. Range and direction of scores for all other reagents tested: negative = normal; trace, 1+, 2+, 3+ = abnormal, the higher the value, the higher the concentration of the reagent tested.

51. Change From Baseline at Weeks 2, 4, 12 and 16 in Clinical Laboratory Parameters Urinalysis: Erythrocytes and Leukocytes [ Time Frame: From baseline to Weeks 2, 4, 12 and 16 ]
    Urine for urinalysis was collected and sent to the central laboratory for analysis. Results are reported according to the amount present in the microscope's field of view at high magnification (/HPF [high-power field]).
52. Change From Baseline at Weeks 2, 4, 12 and 16 in Clinical Laboratory Parameters Urinalysis: Hyaline Casts [ Time Frame: From baseline to Weeks 2, 4, 12 and 16 ]
    Urine for urinalysis was collected and sent to the central laboratory for analysis. Results are reported according to the amount present in the microscope's field of view at low magnification (/LPF [low-power field]).
53. Change From Baseline at Weeks 2, 4, 12 and 16 in Clinical Laboratory Parameters Urinalysis: Bacteria, Yeast Cells, Granular Casts, RBC Casts, Waxy Casts, WBC Casts, Calcium Oxalate Crystals, Triple Phosphate Crystals and Uric Acid Crystals [ Time Frame: From baseline to Weeks 2, 4, 12 and 16 ]

    Urine for urinalysis was collected and sent to the central laboratory for analysis. The evaluation of components in the urine samples such as bacteria, yeast, red blood cells (RBC), white blood cells (WBC), casts and crystals was performed by microscopy. Results are reported according to the amount present in the microscope's field of view at low magnification (/LPF [low-power field]) and high magnification (/HPF [high-power field]).

    Range and direction of scores microscopic identification of urine components:

    • Bacteria: none seen, 1+, 2+, 3+,4+, TNTC (too numerous to count).
    • Other urine components: none seen=normal; few, moderate, many, TNTC = abnormal. The higher the value, the higher the concentration of the component evaluated.
