Cochrane Reviews are regularly updated as new evidence emerges and in response to feedback, and Cochrane Database of Systematic Reviews should be consulted for the most recent version of the review.

Objectives: To describe the number of trials and participants in a typical systematic review from The Cochrane Database of Systematic Reviews.Methods: The number of trials in 1,000 Cochrane systematic reviews in issue 1, 2001 of The Cochrane Database of Systematic Reviews was counted for three categories of trial: included trials, ongoing trials, and trials awaiting assessment for inclusion. (The term trial is used in this paper, although a small number of Cochrane reviews include studies that are not trials.) The total number of participants in included trials was extracted from a sample of reviews.Results: A total of 9,778 trials were included in the Cochrane reviews. There were a further 356 ongoing trials and 1,138 trials awaiting assessment for inclusion. A typical review contained six included trials. Forty percent of the reviews listed ongoing trials and/or trials awaiting assessment for inclusion. Based on a sample of 258 reviews, the median number of participants per review was 945 (interquartile range, 313 to 2,511) per review and 118 (interquartile range, 60 to 241) per trial.Conclusion: This report is a descriptive study of the number of trials and participants in a typical Cochrane review from The Cochrane Library, issue 1, 2001.

Objective The aim of this project was to identify gaps and research waste in the dissemination of fertility evidence in the Cochrane database of systematic reviews (CDSR). Design A research article. Setting The Cochrane Gynaecology and Fertility (CGF) Group’s specialised register of random controlled trials (RCTs). Sample Infertility trials contained in the CGF specialised register, published between the years 2010-2011. Methods Infertility trials from the CGF specialised register were matched, by the specific fertility issue and treatment, to existing Cochrane reviews. Unmatched trials were categorised to develop and prioritise new review topics. Main outcome measures Proportions Results 564 trials, published from 2010 to 2011, were exported from the specialised register and after removing duplicates, 318 trials were found to be already included in a Cochrane review. 187 (37%) of trials were found to be unused, however 115 (23%) of these could be included in an existing CGF SR, if it were updated. 72 trials (14%) were not matched to any review topic and from these, eight new Cochrane review titles were developed. The topic with the largest number of associated ‘unused’ trials, was ‘Traditional Chinese Medicine for women undergoing assisted reproductive techniques’. Conclusions This project was used to consider unused trials, prioritise new review topics and identify those reviews that need to be updated, thereby identifying the gaps in evidence for couples with fertility problems. Keywords research waste, gaps, fertility, infertility, randomized controlled trials, systematic reviews, prioritisation.

IntroductionCitation analysis is a standard tool for measuring the impact and influence of scientific work. One purpose behind controlled trials is to answer clinical and policy questions and to contribute directly or indirectly (contributing to systematic review and meta-analyses) to the production of practice guidance. The citation of trials within systematic reviews and policy or guidance documents therefore represents an authentic and meaningful measure of impact.MethodsAll 136 randomized controlled trials published by the United Kingdom (UK) Health Technology Assessment (HTA) programme in a 10-year period (2006-2015) were identified. Web of Science citation index was used to collect citation data relating to each trial. Altmetrics were used to identify additional policy and guidance documents. Citation data were collected and tabulated, and descriptive statistics produced. Additional data were collected for principal ‘spin-off’ publications.ResultsEighty-eight percent of trials were cited by at least one Cochrane or non-Cochrane systematic review or meta-analysis; 37 percent by at least one Cochrane review (90 Cochrane reviews in total); 85 percent by at least one non-Cochrane systematic review or meta-analysis (365 in total). Forty-four percent of trials were cited by at least one unique piece of published policy or guidance. Mean number of review citations per published trial: 25.30; mean number of systematic reviews/meta-analyses per trial: 3.34; mean number of guidance documents per trial: 0.85. Trial investigators published the primary clinical outcome data in 27 additional peer-reviewed journal articles, generating citations in a further 66 unique reviews and 22 unique guidance documents.ConclusionsBased on the payback model, this sample of 136 UK HTA trials represent meaningful impact: 88 percent of trials were cited in systematic reviews and 44 percent in guidance documents. Chronological data indicate that there might be a sizeable time-lag between publication and impact, especially for policy documents and Cochrane reviews.
