Specific associations between heart rate variability and motor domains in children with attention-deficit/hyperactivity disorder: a comparative study.

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
Objective: This study compared children with Attention-Deficit/Hyperactivity Disorder (ADHD) and typically developing (TD) controls on heart rate variability (HRV) and motor proficiency, and examined their combined role in predicting ADHD symptom severity. Methods: Twenty-nine children with ADHD and 33 TD children, matched for age and sex, underwent assessment. ADHD symptoms were assessed using the Strengths and Weaknesses of ADHD Symptoms and Normal Behavior (SWAN) scale, motor skills were evaluated using the Movement Assessment Battery for Children-2 (MABC-2), and resting-state HRV was recorded via a 5-minute electrocardiogram. Results: The ADHD group demonstrated significantly poorer performance across all MABC-2 domains (fine motor, coordination, balance, total score; all Conclusion: Children with ADHD show concurrent deficits in motor skills and autonomic regulation. HRV, particularly SDNN, serves as a robust physiological marker for symptom severity, suggesting that integrated assessment of motor and autonomic function provides a more comprehensive understanding of ADHD.
