The investigators limited their focus to sociodemographic and medical factors. In addition, they did not study whether adherence trajectories affected health outcomes. However, this study is part of a longitudinal study, and the investigators noted that they are "currently examining psychosocial factors that contribute to adherence trajectories."
The study was funded by a grant from the National Institutes of Health. Dr. Modi disclosed that she has been a consultant for Novartis Pharmaceuticals Inc. Another study author disclosed speaker and adviser relationships with companies that manufacture antiepileptic drugs.
