Radical Prostatectomy or Watchful Waiting in Prostate Cancer

Describe how patients and clinicians (researchers) were blinded (if at all) to the treatment (or intervention). Describe the implications of not undertaking this process.

Was the assignment of patients to treatments randomized? Was the randomization list concealed? Were patients and clinicians kept ‘blind’ to treatment? Was the follow-up of patients sufficiently long and complete? Were the groups similar at the start of the trial?
