| Aim | To assess Cochrane review protocols published in 2010, their characteristics, and whether they were published by February 2018. Additionally were surveyed for reasons for nonpublication of protocols to assess factors predicting the time to publication |
| Level of Investigation | Descriptive |
| Summary of Findings | From 576 included Cochrane review protocols, 77.4% were published as a full review and 22.6% were still unpublished in February 2018. Median time from protocol publication to publication of the completed review was 2.78 years. Common reasons for nonpublication were: lack of time to work on the review; topic was out of date because of long Cochrane production process or Cochrane review group rejected the completed reviews and the authors published them elsewhere. |
