Mean Change in the Number of Moderate to Severe Vasomotor Symptoms Per Day

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
