What makes a research study evidence based?
Evidence-based research means that the information you use to make decisions about patient care is based on sound research, not opinion. This means you must search several sources (published articles in medical journals or in electronic form) for data, results and conclusions of valid, reputable studies.
What is best research evidence?

What is low quality evidence?
In the GRADE approach to quality of evidence, randomised trials without important limitations constitute high quality evidence. Observational studies without special strengths or important limitations constitute low quality evidence. Limitations or special strengths can, however, modify the quality of the evidence.
What is quality of evidence and why is it important to clinicians?
