• OQAQ |
| Aim | To assess the methodological quality (OQAQ) of renal systematic reviews published across several databases in 2005. |
| Level of Investigation | Analytical |
| Summary of Findings | Of the 90 included renal systematic reviews published across several databases in 2005, the average OQAQ score was 6 (out of 9). Major methodologic flaws included (44/90; 40%) failure to assess the methodologic quality included studies. 51 of 90 (57%) reviews failed to show evidence that they attempted to minimize their bias during the process of selection of studies for analysis by having only one person select eligible studies, or they lacked a priori criteria for inclusion. Factors that were independently associated with higher methodologic quality were a lack of language restriction in the literature search, an attempt to contact primary study authors, and an explicit statement regarding sources of funding. |
