Abstract
Sirs—We read with interest the article by Dickersin on systematic reviews and meta-analysis of observational studies.1 She notes obstacles for conducting systematic reviews of observational studies as compared to those of intervention studies (randomized trials) of medical and non-medical forms of care. She also suggests steps to improve their methodological quality.Keywords
