• AMSTAR 2 |
| Aim | To assess the presence of spin (Yavchitz et al 2016) and methodological quality (AMSTAR 2) in systematic reviews of interventions from the top 5 general medical journals (1. The Lancet; 2. Journal of American Medical Association; 3. British Medical Journal; 4, Annals of Internal Medicine ; and 5. JAMA Internal Medicine) published between January 2011 and November 2017. |
| Level of Investigation | Analytical |
| Summary of Findings | From 196 systematic reviews of interventions from the top 5 general medical journals (1. The Lancet; 2. Journal of American Medical Association; 3. British Medical Journal; 4, Annals of Internal Medicine ; and 5. JAMA Internal Medicine) published between January 2011 and November 2017, 94% of abstracts and 67% of full texts presented at least one item of the 7-item SPIN checklist. The authors of the letter also observed critically low overall confidence in 77% reviews, 19% with low, 3% with moderate and only 1% with high overall confidence and report an association between abstracts with higher levels of spin and reviews with critically low methodological quality (ß 0.22; 95%CI: 0.14, 0.63), when compared to reviews of high methodological quality (ß -0.12; 95%CI: -2.69, 0.18). |
