Fig. 1 Survival graph showing time to publication (in a peer-reviewed journal) of all studies within the dataset. Vertical bars indicate right censored studies (those which had not published at the end of the study period on the 11th Jan 2011 when the ClinicalTrials.gov search took place).

Fig. 2 A. Survival graph showing time to publication of studies, categorised according to funding body listed on ClinicalTrials.gov. There were only 5 included studies in the “NIH or US Gov” group. There was no significant difference between groups in the proportion of studies which published within the follow up period. B. Survival graph showing time to publication of studies grouped by study Phase. Phase I studies were least likely to publish results. Vertical bars on each plot indicate right censored studies.
