Authors: Andrea C. Tricco, Jamie Brehaut, Maggie H. Chen, David Moher

DOI: 10.1371/journal.pone.0003684

Abstract Summary

Only 80% of Cochrane review protocols were published as full reviews after 8+ years, with a median publication time of 2.4 years. Reviews requiring protocol amendments took significantly longer to publish. These delays could impact evidence-based decision-making. The findings suggest streamlining processes and better author support are needed to accelerate Cochrane review publication.

Study finds only 80% of Cochrane review protocols are published after 8+ years, with median 2.4-year delay. Delays may bias evidence availability and affect clinical decisions based on incomplete data.
