^aTotal number of responders needed to show a clinically relevant difference in symptoms (moderate vs. severe bothersome menopause-related symptoms) with an 80% power and 5% level of significance. Low numbers indicate a high discriminating ability.
df = Degrees of freedom, HF = hot flushes, DNS = day-and-night sweats, GS = general sweating, MSSP = menopausal-specific sleeping problems, EM = emotional, MEM = memory, SH = skin-hair, PHY = physical, ABD = abdominal, URIN = urin-vaginal, SEX = sexual
