Comparative analysis reveals open access increases citations across 27,197 articles regardless of mandates, indicating higher impact stems from wider access rather than author self-selection bias.

Key Points

To determine whether the open access citation advantage is causal or primarily driven by author self-selection bias toward making higher-quality work freely available.
Analyzed N = 27,197 articles published between 2002 and 2006 across 1,984 academic journals.
Compared citation outcomes between self-selective self-archiving and institutionally mandated self-archiving policies.
Applied logistic regression adjusting for article age, journal impact factor, co-author count, reference count, page length, discipline, article type, and country.
The open access advantage remained equally elevated under mandatory self-archiving as it did under self-selected archiving, confirming an independent and causal effect.
Citation gains skewed heavily toward top-tier research, aligning with general citation dynamics where the top 20% of articles received approximately 80% of all citations.
