Common cause versus dynamic mutualism: Insights into ADHD's common comorbidities.
Article in JCPP advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Contemporary classification systems differ in their conceptualization of ADHD as either an externalizing or neurodevelopmental condition, with both perspectives promoting the common cause model as an explanation of ADHD's comorbidity. An alternative theory, dynamic mutualism, proposes that ADHD's comorbidity emerges through reciprocal interactions among symptoms over time, as opposed to a common cause. Methods: We tested the common cause and the dynamic mutualism theories in explaining the associations between aspects of ADHD (i.e., ADHD, inattention, hyperactivity/impulsivity, cognitive disengagement) and the neurodevelopmental and externalizing spectra across four waves of the Adolescent Brain Cognitive Development (ABCD) Study data ( Results: Results largely supported the common cause theory in explaining the developmental links between ADHD and both the externalizing and neurodevelopmental spectra. Findings varied across ADHD subdimensions, although not substantially, with hyperactivity/impulsivity more closely linked to the externalizing spectrum and cognitive disengagement more closely linked to the neurodevelopmental spectrum. Conclusion: ADHD is best conceptualized as a disorder that bridges both the externalizing and neurodevelopmental domains, rather than fitting exclusively within either category. Given the assessment structure of the ABCD Study, there was more support for the common cause model compared with dynamic mutualism.
