1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveIn this study, we examined antidepressant (fluoxetine) medication adherence in children and adolescents with major depressive disorder (MDD). Using electronic monitoring (EM) as the "reference standard," we compared various methods of measuring antidepressant medication adherence (including EM, pill counts, and medication diaries) among children and adolescents with MDD and examined the relationship between EM medication adherence and depression severity across time. We then suggested recommendations for clinical researchers and practicing clinicians regarding medication adherence assessment.

methodThirty-one child and adolescent outpatients with MDD who enrolled in a 12-week open trial of fluoxetine had their antidepressant medication adherence assessed at each visit, using EM, pill counts, and parent and patient medication diaries. Depression severity was assessed by the Children's Depression Rating Scales-Revised at each visit.

resultsTwelve-week least squares mean estimates of medication adherence for the entire sample was high, regardless of the adherence assessment method, although the overall adherence among the four methods (EM, pill, parent diary, patient diary) was significantly different (87.5% vs. 90.6% vs. 93.1% vs. 93.3%, respectively, p=0.0002). Adjusted mean symptom severity was significantly lower for the EM "adherent" group than for the EM "nonadherent" group over the 12 weeks of treatment (35.6 vs. 43.8, p=0.008).

conclusionOverall, EM medication adherence for the depressed youth in this study is high. Compared with EM, there is a tendency of pill counts and medication diaries to overestimate medication adherence. However, pill count adherence better approximates EM adherence, and compliance with returning medication diaries is poor. Youth who are adherent to fluoxetine treatment have lower symptom severity over the course of treatment. Recommendations are provided.
