Quality assessment methods for drug class reviews for the Drug Effectiveness Review Project This appendix outlines the methods used by the Oregon Evidence-based Practice Center, based at Oregon Health & Science University, and any subcontracting Evidence-based Practice Centers in producing drug class reviews for the Drug Effectiveness Review Project. The procedure outlined in this appendix ensures that the reviews created by using these methods are scientifically defensible, reproducible, and well documented. These methods were adapted from the Procedure Manual developed by the Methods Work Group of the United States Preventive Services Task Force (version 1. All included studies and systematic reviews are assessed for quality and assigned a rating of “good,” “fair,” or “poor”. Studies that have a fatal flaw in 1 or more criteria are rated poor quality. Studies that meet all criteria are rated good quality. As the “fair-quality” category is broad, studies with this rating vary in their strengths and weaknesses: The results of some fair quality studies are likely to be valid, while others are only probably valid. A poor-quality trial is not valid: Its results are at least as likely to reflect flaws in the study design as a true difference between the compared drugs. Controlled Trials Assessment of Internal Validity 1. Was the assignment to treatment groups really random?

Were the groups similar at baseline in terms of prognostic factors? Were outcome assessors blinded to the treatment allocation?
