For recommendations in The Dr Oz Show, evidence supported 46%, contradicted 15%, and was not found for 39%. Results We could find at least a case study or better evidence to support 54% (95% confidence interval 47% to 62%) of the 160 recommendations (80 from each show). Secondary outcomes included topics discussed, the number of recommendations made on the shows, and the types and details of recommendations that were made. Main outcomes measures Percentage of recommendations that are supported by evidence as determined by a team of experienced evidence reviewers. A group of experienced evidence reviewers independently searched for, and evaluated as a team, evidence to support 80 randomly selected recommendations from each show. Interventions Investigators randomly selected 40 episodes of each of The Dr Oz Show and The Doctors from early 2013 and identified and evaluated all recommendations made on each program.
