Question Posted 11/28/14:
Dear Sir or Madam,

we are interested in a study of dementia and the use of the anti-diabetic drug pioglitazone. Therefore, we like to know whether
1) you have information about the medication with pioglitazone in your data, and
2) if so, are there enough case numbers in each, the exposed and un-exposed group (case/controls)?

Thank you very much for your help.

Sincerely yours,
Anne Fink

Dear Anne,

Data is collected on all medications that subjects are currently taking. If you apply for data access, you may explore the concurrent medications data to see whether there are enough subjects to fit your research needs.
