P300 event-related potentials as diagnostic biomarkers for attention deficit hyperactivity disorder in children.

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
Objectives: This study aimed to evaluate the utility of P300 event-related potentials (ERPs) as neurophysiological biomarkers for diagnosing attention deficit hyperactivity disorder (ADHD) and to establish preliminary diagnostic thresholds for their use. Methods: A total of 106 children diagnosed with ADHD and 66 healthy controls were enrolled. Using a visual Oddball paradigm, P300 parameters were recorded at Fz, Cz, and Pz zones. Key metrics analyzed included P300 amplitude and latency as well as reaction time and correct responses. Statistical tests and logistic regression analysis identified significant group differences, while receiver operating characteristic (ROC) analysis determined the diagnostic performance of these parameters. Results: Children with ADHD exhibited significantly lower P300 amplitudes and longer latencies across all electrode sites compared to controls. Logistic regression identified Cz amplitude (p = 0.001), Pz amplitude (p = 0.011), maximum reaction time (p = 0.037), and correct response count (p < 0.001) as significant predictors of ADHD. ROC analysis showed that Cz amplitude, Pz amplitude, maximum reaction time, and correct responses achieved AUCs of 0.81, 0.75, 0.72, and 0.86, respectively, with sensitivities ranging from 66% to 80% and specificities from 61% to 95%. These results underscore the diagnostic potential of both electrophysiological and behavioral markers in ADHD assessment. Conclusions: Cz and Pz amplitude, maximum reaction time, and correct responses each demonstrated strong diagnostic utility for distinguishing ADHD from typically developing children. The use of these neurophysiological and behavioral indicators as objective complements to traditional clinical assessments.
