How many times have you served as a clinical investigator?

Medicine advances in large part on the basis of clinical trials in which new treatments or diagnostic methods are evaluated.

These trials are often conducted at large medical centers, but in many instances, community-based physicians participate as investigators and help to accrue patients, especially for trials in which a treatment is being tested for a relatively uncommon disease or condition.

Renal & Urology News would like to know the extent of nephrologist and urologist participation in clinical trials, so please answer the following poll question.
