Thanks to our peer reviewers

4 marks the completion of Volume 9 of Learning Health Systems.An international, trans-disciplinary, open access publication, the journal has advanced research and scholarship on learning health systems in partnership with our reviewers.With indexing in multiple major sources and an Impact Factor of 2.6, we have achieved a publication milestone that signals a sustainable, positive trajectory.Articles from the journal had more than 142,000 full-text views in 2024.We continue to diversify the offerings of the journal through special issues and special collections, and through the supplemental issue published each year in collaboration with Academy Health.We are keenly aware that these achievements would not have happened without the dedicated efforts and insightful comments of all those individuals who accepted invitations to review submitted articles.With busy schedules and full commitments, these individuals found the time and energy to contribute their expertise to our authors to help ensure that their papers met (and often exceeded) the journal's high standards for publication.
