Time to Publication Among Completed Clinical Trials
Open accessAbstract
Prior studies have shown that 25% to 50% of clinical trials are never published.[1][2][3][4] However, among those published, we know little about the length of time required for publication in the peer-reviewed biomedical literature after study completion.Ioannidis previously demonstrated that a sample of randomized phase 2 and 3 trials conducted between 1986 and 1996 required nearly 2.5 years for publication, 5 while our more recent study of National Institutes of Health (NIH)-funded trials found that average time to publication was almost two years.4 We sought to determine time to publication for a recent and representative sample of trials published in 2009. METHODSWe examined clinical trials published during the 2009 calendar year that were indexed via MEDLINE and linked to a ClinicalTrials.govidentifier (NCT Number).6 We excluded articles that were not the first publication reporting on the clinical trial by reviewing article text for citations to and searching MEDLINE for earlier trial publications.We imputed completion dates based on the subject enrollment dates and the longest period of follow-up required for any outcome measure reported in the article.For trials without enrollment dates, we used the completion date provided on ClinicalTrials.gov;

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
