Aim A letter highlighting seemingly discrepant conclusive remarks between a health technology assessment report and a published systematic review about efficacy of etanercept and infliximab for the treatment of psoriatic arthritis.
Level of Investigation Descriptive
Summary of Findings The authors replicate verbatim quotes from the conclusions from two reports of the same research which, when presented without the economic analysis, represents discrepant confidence in the clinical efficacy of both interventions. The published systematic review also did not reference the earlier heath technology assessment.
