The recent systematic review of interventions to promote antiretroviral therapy (ART) adherence by Mathes and colleagues  published in HIV Medicine contains several methodological flaws that lead to an overly pessimistic depiction of the state of the literature; indeed, it contradicts other widely cited reviews on the topic that demonstrate the efficacy of such interventions to improve both adherence and viral load (VL) [2−5]. Curiously, the only prior review cited was Simoni , and only then to support a lack of efficacy for adherence interventions, which is contrary to the main findings of that review. This bias in citation creates unfounded authority for the authors' dire conclusions that ‘adherence enhancing interventions are not promising’.
