Patient characteristics' moderation of multinutrients treatment response in school-age children with attention deficit hyperactivity disorder.
Trial report in European child & adolescent psychiatry, 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
objectiveThis study analyzed data from the Micronutrients for ADHD in Youth (MADDY) 8-week RCT to identify moderators of treatment response to multinutrients, i.e., patient characteristics likely to predict optimal benefit based on the Clinical Global Impression-Improvement (CGI-I)- scale.
methodsClassification tree analysis investigated demographic and clinical history variables as potential moderators of treatment response. Effect sizes (ES) with confidence intervals (CI) were generated using bivariate analysis of risk difference of proportions derived from the classification tree between-treatment effects stratified by the moderator variable.
resultsThe classification tree showed a higher response rate among multinutrient-treated children (n = 70) with university-educated parents compared to those with parents with less than a university education (64% vs. 36%); a finding also supported by the bivariate analysis (ES = 0.35, 95% CI = 0.03-0.67). Within university-educated parents, a larger percentage of children with past ADHD medication use were responders compared to no past ADHD medication use (83% vs. 52%). Classification tree also revealed that among multinutrient-treated children with university-educated parents without past ADHD medication, higher baseline CGI-Severity score was responders compared to lower baseline score (67% vs. 33%). Bivariate analysis predicted higher response in participants whose parents reported alcohol use disorder (ES = 0.43, 95% CI = 0.10-0.76), or illegal drug use (ES = 0.68, 95% CI = 0.52-0.84), or learning problems (ES = 0.44, 95% CI = 0.13-0.75).
conclusionsParent education level, substance use disorder or learning problems, and child's previous medication use moderated multinutrient response in children with ADHD. These findings have implications for future research and clinical practice.
