Once you locate articles, you'll want to appraise the evidence. Some questions to consider:

1. How serious it the risk of bias?
   • examine specific validity criteria based on study design
   • focus on how well the authors report their methods; note what is missing or unclear
   • look at who funding the study
2. What are the results?
3. Will the results help patient care?
