The work produced a paper, “Who has long-COVID? A big data approach,” that was recently peer-reviewed and accepted for publication by Lancet Digital Health, said co-author Dr. Tell Bennett, head of the Informatics and Data Science section in the Department of Pediatrics at the University of Colorado School of Medicine. The paper was also the first produced by the National Institutes of Health-funded RECOVER study, which is recruiting patients nationwide to study long COVID, Bennett said.
