RESUMEN
OBJECTIVES: To characterise redactions in clinical trials and estimate a time when all protocols are fully removed (RAPTURE). DESIGN: Redacted cross sectional study. SETTING: Published phase 3 randomised controlled trials from 1 January 2010 to ââââââââââââââ. PARTICIPANTS: New England Journal of Medicine, ââââââââââ, and Journal of the American Medical Association. MAIN OUTCOME MEASURES: âââââ ââââââââ ââââââââââââââ ââââââ ââââââââââ ââââââââ ââââââââ ââââââââââ âââââââââââ ââââââââââââ ââââââââââââ ââââââââââââââââââââââââ ââââââââââââââââââ RESULTS: ââââââââââââââââââââ met the inclusion criteria, with 268 (56.7%) research protocols available and accessible. The rate of redactions in protocols has increased from 0 in 2010 to 60.8% in 2021 (P<0.001). The degree of data redaction has also increased, with the average cumulative redactions among industry funded trials rising from 0 in 2010 to 3.5 pages in 2021 (P<0.001). Modelling predicts that RAPTURE is expected to occur between 2073 and 2136. Redactions featured predominantly in ââââââââ sponsored trials and mostly occurred in the statistical design. CONCLUSIONS: This study highlights the rise in protocol redactions and predicts that, ââââââââââââââââââââââââââââââââââââââââââ will be entirely redacted between 2073 and 2136. A legitimate rationale for the redactions could âââ be found. A multipronged strategy against protocol redactions is required to maintain the integrity of science. AVAILABILITY: This paper is partially redacted, but for the sake of âââââââââââ, a version without any redactions can be found in the supplementary material.
