Experts question research on HRT

MILLIONS of women may have been misled about the effect of hormone replacement therapy (HRT) on heart disease risk because of flawed research, experts claimed yesterday.

A new study has raised serious doubts over a pivotal US investigation that overturned preconceptions about HRT and the heart.

Scientists said the Women’s Health Initiative (WHI) study, which reversed many experts’ opinions about HRT, could not possibly have detected a beneficial effect on heart health given the way it was designed.
