| Aim | To assess the general conduct/quality of systematic reviews of observational studies of non-therapeutic interventions conducted between 2005-2008. |
| Level of Investigation | Descriptive |
| Summary of Findings | Of the 145 included systematic reviews of observational studies of non-therapeutic interventions conducted between 2005-2008, fewer than half met each quality criterion; 49% reported study flow, 27% assessed grey literature, 2% abstracted sponsorship of individual studies, and none abstracted the disclosure of conflict of interest by the authors of individual studies. Planned, formal internal quality evaluation of included studies was reported in 37% of systematic reviews. The journal of publication, topic of review, sponsorship, and conflict of interest were not associated with better quality. |
