Primary Outcome Measures:

Mean Change in the Number of Moderate to Severe Vasomotor Symptoms Per Day [ Time Frame: baseline to week 12 ] [ Designated as safety issue: No ]
Patients completed a daily diary to record the number of mild, moderate and number of moderate or severe vasomotor symptoms [hot flushes and sweating] experienced each day.

Mild, moderate and severe hot flushes and sweating were defined as follows:

Mild = sensation of heat without sweating Moderate = sensation of heat with sweating, ability to continue activity Severe = sensation of heat with sweating, causing discontinuation of activity
Mean Change the Severity of Moderate to Severe Vasomotor Symptoms [ Time Frame: baseline to week 12 (12 weeks) ] [ Designated as safety issue: No ]
Patients completed a daily diary to record the number of mild, moderate and severe vasomotor symptoms experienced each day.

Mild, moderate and severe were defined as follows:

Mild = sensation of heat without sweating Moderate = sensation of heat with sweating, ability to continue activity Severe = sensation of heat with sweating, causing discontinuation of activity Severity of hot flushes was measured on a scale of none = 0, mild = 1, moderate = 2 and severe = 3.
