We Welcome Your Comments


Thank you for visiting the NLM Comparative Effectiveness Research (CER) Filters project. Our intent for this tool is to assist the broad array of clinical and health services researchers, policy analysts, and the public to access high quality research, both completed and in progress, that will inform their investigations of questions related to comparative effectiveness. Filters – structured searches – provide a means to more rapidly and consistently identify research of interest, which we hope will both help individuals and provide a common set of reference for discussion of this emerging field.

Help us improve this site:

  • Did the search filters provide you with relevant information?
  • Do you have a suggestion to improve the current CER filters?
