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

backgroundAttention-deficit/hyperactivity disorder (ADHD), characterized by inattention and hyperactivity-impulsivity, profoundly influences cognitive and behavioral development. Compared with their typically developing (TD) counterparts, children diagnosed with ADHD consistently exhibit impaired performance, which manifests as delays in response inhibition, interference selection, and working memory. We hypothesized that with increasing age, the attentional differences observed in younger children would progressively diminish, and that these developmental changes would be associated with behavioral and emotional problems.

methodsWe analyzed data from 131 children diagnosed with ADHD, sourced from the psychiatric outpatient departments of two hospitals, alongside data from 167 TD children aged 4-12 years. Using analysis of variance, we investigated differences in Comprehensive Attention Test (CAT) scores, intelligence quotients, and the Korean version of the Child Behavior Checklist (K-CBCL) scores between children with ADHD and their TD peers.

resultsCompared with their TD counterparts, children diagnosed with ADHD exhibited lower intelligence quotient scores across multiple subscales and elevated levels of diverse behavioral problems. Age-related patterns unveiled shifts in CAT scores. K-CBCL externalizing and internalizing problem scale and CAT scores were correlated.

conclusionThis study revealed age-related patterns of cognition among pediatric patients with ADHD when compared with a non-ADHD control group. With maturation, developmental delays may lessen, and attention improvement follows a discernible sequence, commencing with basic attention, followed by inhibition and ultimately, interference selection. Furthermore, age-dependent correlations between CAT and K-CBCL scale scores were identified. These findings highlight the clinical importance of considering age-specific patterns of cognitive and behavioral characteristics in the assessment of ADHD.
