What appraisal question would assist the reviewers in identifying the level of evidence the CPGs were developed from?
1) Were any of the guideline developers funded researchers of the reviewed randomized control studies?
2) Is each recommendation identified by the level or strength of evidence on which it is based and linked with the scientific evidence?
3) Was an explicit (how decisions were made), sensible, and impartial process used to identify, select, and combine the evidence?
4) Do the guideline make explicit recommendations (reflecting value judgments about outcomes)?
