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

This longitudinal, population-based cohort study examines the direct and indirect associations between adolescent Attention-Deficit/Hyperactivity Disorder (ADHD) and/or Oppositional Defiant Disorder (ODD) symptoms and adult incomes. Moving beyond a simple direct link, our model explores how ADHD and/or ODD symptoms indirectly affect the accumulation of human, social, and health capital, which in turn may affect productivity and income. The population was drawn from members of the Northern Finland Birth Cohort 1986 (NFBC1986) who had ADHD and ODD symptoms assessed at age 16 using the Strengths and Weaknesses of ADHD Symptoms and Normal Behaviours (SWAN) scale. The results indicate a significant indirect negative effect of adolescent ADHD and ADHD + ODD symptoms on adult incomes. This effect was most pronounced in males with ADHD + ODD, who experienced a 25% income reduction via human capital (education) and an 18% reduction via health capital (presence of psychiatric disorders other than ADHD or ODD). Social capital did not mediate the association. The model was adjusted for work experience, white-collar status, marital status, parenthood, self-rated health, educational attainments of the participants' parents and family type during adolescence. Notably, no direct effect of adolescent ADHD and/or ODD symptoms on adult incomes was observed. These findings highlight the potential of educational and healthcare investments to reduce the income disparities associated with ADHD and ODD symptoms in the general population.
