Medication adherence and influencing factors in children and adolescents with attention deficit hyperactivity disorder (ADHD): a systematic review and meta-analysis.
Synthesis in Frontiers in pharmacology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Background: Medication non-adherence is widely occurring in children and adolescents with ADHD, which may lead to adverse consequences. However, the pooled adherence rate and influencing factors are inconsistent in different studies. Methods: We searched PubMed, Embase (Ovid), Cochrane Library, and four Chinese Databases from inception to 20 February 2024. All types of studies were included. Two researchers independently extracted data and assessed the risk of bias based on ROBINS-I, NOS, and AHRQ. A random-effects meta-analysis was conducted to pool the prevalence estimates and factors that can be combined. Results: After screening 2,360 publications, 63 studies were finally included, involving 450,759 participants. The general quality of the included studies was moderate to high quality. Adherence rates were reported in 50 studies, and a pooled adherence rate was 43.6% (95% Confidence Interval [CI] 39.0%-48.3%). The sensitivity analysis shows robust study results. However, both the primary analysis and the sensitivity analysis indicated high heterogeneity. The results of Meta-analysis identified five factors influencing adherence, of which female (Odds Ratio [OR] = 1.07, 95%CI:1.03-1.11), fewer medication doses (OR = 0.45, 95%CI:0.27-0.75), parental agreement with the medication plan (OR = 1.87, 95%CI:1.16-3.02), single-child families (OR = 1.80, 95%CI:1.29-2.52), and medication education for parents (OR = 6.34, 95%CI:3.97-10.12) can improve medication adherence. Besides, we also identified seven factors influencing adherence by qualitative analysis. Conclusion: Medication adherence is challenging for children and adolescents with ADHD, moreover, the meta-analysis of adherence rates showed high heterogeneity. We identified five modifiable factors by meta-analysis that are related to medication adherence, while other factors require further research.
