The million women study: a critique.
The regulatory authority in the UK, the Committee on Safety of Medicines, issued advice to health professionals on the day the results of the Million Women Study (MWS) were published. This course of action was undertaken before review of the study by the international medical and scientific community. We have reviewed the methodology of the MWS. It is our belief that the flaws in the design render the results largely uninterpretable because built in biases have affected risk estimates.
