Group‐Based Trajectory Models: Assessing Adherence to Antihypertensive Medication in Older Adults in a Community Pharmacy Setting
Sign Up to like & getrecommendations! Published in 2018 at "Clinical Pharmacology and Therapeutics"
DOI: 10.1002/cpt.865
Abstract: Antihypertensive medication nonadherence is highly prevalent, leading to uncontrolled blood pressure. Methods that facilitate the targeting and tailoring of adherence interventions in clinical settings are required. Group‐Based Trajectory Modeling (GBTM) is a newer method to… read more here.
