When is Enough, Enough? How the Absence of Dose-Determination Trials Impedes Implementation of HIV Behavioral Interventions.

Carefully controlled clinical trials have determined that theory-based behavioral interventions delivered by adherence nurses, professional and paraprofessional counselors, and case managers improve ART adherence and viral suppression.
