Medical research often takes a long time to reach the public. A new study protocol is being developed to understand why this happens. It will look at the time between when a paper is finished and when it appears online. This gap is called publication lag. The plan is to review high-quality medical journals and systematic reviews published between 2023 and 2025. Researchers want to see if slow publishing is a real problem or just a side effect of complex science. They will check how well journals follow timeliness rules and what causes these delays. The study will not report on safety because it is a planning document, not a finished trial. It is important to remember that a long wait does not always mean the journal is slow. Sometimes the authors need more time to fix their work before it can be published. High-performing journals might hide these delays because they are very efficient at their own tasks. This new work aims to separate the real issues from the noise.
Protocol for a meta-epidemiological study on publication lag in systematic reviewsNew study protocol looks at why medical papers take so long to appear online

This document is a protocol for a meta-epidemiological study. Its scope is to analyze publication lag—the interval from last search date to online publication—in interventional, RCT-based meta-analyses published in top-tier general medical journals and the Cochrane Database of Systematic Reviews (CDSR) between 2023 and 2025. The study will also assess compliance with AMSTAR 2 timeliness standards and identify independent predictors of publication delay.
The authors do not report main results, as this is a protocol. They acknowledge key limitations, including reliance on publicly available dates, which precludes a granular distinction between author-related revisions and editorial processing durations. They also note that observed lag may overstate editorial inefficiency if journals attract more complex reviews requiring extensive author revisions, and that high-performance editorial workflows might mask prolonged author delays.
Practice relevance is not reported. The protocol does not describe a specific study population, intervention, comparator, or adverse events, as these details are not provided in the source.
