Participant Flow
Men were randomized at 427 study sites in the US, Puerto Rico and Canada between August 22, 2001 and June 24, 2004.
Prior to randomization, there was a three month formal pre-randomization period with no placebo run-in capsules to give potential participants to decide if they would agree to stop disallowed over-the-counter supplements of selenium or vitamin E. By returning for randomization, they exhibited their willingness to adhere to the trial.

PRIMARY outcome
Timeframe: Every six months for 7 to 12 years depending on when the participant was randomized.Population: All randomized eligible men not at 2 sites for which the DSMC said the data could not be used due to participant and data management issues as well as regulatory problems.
Participants are seen at the study site every six month for an update of medical events. Prostate cancer diagnosis is based on participant report followed by the submission of a pathologic sample to central pathology review for confirmation.

Participants are seen at the study site every six month for an update of medical events. Cancer diagnoses are based on participant report. Medical records for non-prostate cancers were collected but they were not pathologically confirmed. If the participant has been diagnosed with prostate cancer, study site visits are once a year. Follow-up was planned for seven to 12 years depending on when the participant was randomized.

Deaths include those reported as SAEs as well as non-SAE deaths as this was a prevention trial with older generally healthy men at baseline who were followed for a long time.
