Subgroup analysesSubgroup analyses by dose of BHT suggested that higher doses of BHT may be associated with more effectiveness but also higher risk of adverse effects .
There was low to moderate quality evidence that BHT in various forms and doses is more effective than placebo for treating moderate to severe menopausal hot flushes .
There was some evidence to suggest that higher doses of BHT are associated with greater effectiveness but also with higher risk of adverse effects .
No data are yet available about the safety of BHT with regard to long-term outcomes such as heart attack , stroke and breast cancer .
BACKGROUND Various hormone therapies ( HT ) are available to treat  menopausal vasomotor symptoms .
Bioidentical hormones are chemically identical to those produced by the human body , and several types are well-tested and available on prescription .
Many women have opted for bioidentical hormone therapy ( BHT ) on the assumption that it is safer than other forms of HT .

The effect of hormone therapy on women's quality of life in the first year of the Estonian Postmenopausal Hormone Therapy trial
Background For postmenopausal women , the main reason to start hormone therapy ( HT ) is to reduce menopausal symptoms and to improve quality of life ( QOL ) . The aim of this study was to analyse the impact of HT on different aspects of symptom experience and QOL during a r and omised trial . A total of 1823 postmenopausal women were recruited into the Estonian Postmenopausal Hormone Therapy ( EPHT ) trial in 1999–2001 . Women were r and omised to blind HT , open-label HT , placebo or non-treatment arm . After one year in the trial , a question naire was mailed and 1359 women ( 75 % ) responded , 686 in the HT arms and 673 in the non-HT arms . Mean age at filling in the question naire was 59.8years . The question naire included Women 's Health Question naire ( WHQ ) to assess menopause specific QOL of middle-aged women together with a 17-item question naire on symptoms related to menopause , a question about painful intercourse , and a question about women 's self-rated health . Results After one year in the trial , fewer women in the HT arms reported hot flashes , trouble sleeping , and sweating on the symptom question naire . According to WHQ , women in the HT arms had fewer vasomotor symptoms , sleep problems , and problems with sexual behaviour , but more menstrual symptoms ;  HT had no effect on depression , somatic symptoms , memory , attractiveness , or anxiety . A smaller proportion of women reported painful intercourse in the HT arms . There were no significant differences between the trial arms in women ’s self-rated subjective health . Conclusions The results from the EPHT trial confirm that HT is not justified for treating symptoms , other than vasomotor symptoms , among postmenopausal women . WHQ proved to be a useful and sensitive tool to assess QOL in this age group of women
