Publication Lag in RCT-Based Meta-Analyses from Top Journals and Cochrane, 2023-2025

A meta-epidemiological study protocol analyzes publication delays in systematic reviews. The dataset likely contains records of interventional, RCT-based meta-analyses published in top-tier general medical journals and the Cochrane Database of Systematic Reviews between 2023 and 2025. Jia Song authored this protocol, which was uploaded to figshare in April 2026.

Use Cases

• Quantify publication lag intervals based on last search and publication dates mentioned in the description
• Assess compliance with AMSTAR 2 timeliness standards based on the methodological framework
• Compare editorial performance between top-tier journals and the Cochrane Database of Systematic Reviews based on the study's comparison goal
• Identify independent predictors of publication delay using multivariable regression analysis described in the protocol

Strengths

• Focuses on a specific time range (2023-2025) for current analysis
• Explicitly compares two major sources of systematic reviews: top-tier journals and the Cochrane Database
• Protocol is registered (OSF.io/cjtk), indicating a structured research plan

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
