Clinical trial results information extraction

Matt Williams suggests that it would be very useful to be able to extract clinical trial results from the literature. He gives as a couple of examples papers returned in pubmed searches:


 * "Alzheimer Disease"[Mesh&#93; AND "Drug Therapy"[Mesh&#93; limited to Humans, Randomized Controlled Trial, English
 * "Breast Neoplasms"[Mesh&#93; AND ("antineoplastic agents" [Mesh&#93; AND "Prognosis"[Mesh&#93;) AND (methods[Title/Abstract&#93;)  limited to Female, Randomized Controlled Trial, English, All Adult: 19+ years

The desired information to extract is:


 * The patient group involved (not down to the level of entry criteria, but as old/ young/ breast cancer, etc.)
 * The study type/ design
 * The agents involved
 * The outcome measure (Overall Survival, Disease Free Survival, Progression Free Survival, etc.)
 * The direction & magnitude of change
 * Author's name and affiliations would also be interesting.
