The diagnostic effect of integrated visual and auditory continuous performance and event-related potentials in ADHD.

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
objectiveThe development of objective assessment tools for attention deficit hyperactivity disorder (ADHD) has become a hot research topic. The aim was to explore the value of the P300 wave and integrated visual and auditory continuous performance test (IVA-CPT) in diagnosing ADHD.
methodsWe enrolled 30 patients with ADHD and 30 age-matched healthy volunteers in a prospective study to evaluate differences in IVA-CPT and P300 indexes using student t test. These tools' accuracy in identifying ADHD patients was evaluated using receiver operating characteristic curve analysis. Additionally, the correlation between P300 and IVA-CPT in ADHD patients was evaluated using Pearson correlation analysis.
resultsCompared with healthy volunteers, ADHD patients showed longer latency and lower amplitude, and had lower scores of IVA-CPT (P<0.01). There was no significant difference of latency, amplitude, and area below the amplitude of the P300 wave and in the score of IVA-CPT for age and gender within-ADHD groups (P>0.05). Moreover, receiver operating characteristic (ROC) curve showed high accuracy of P300 and IVA-CPT in identifying ADHD patients. Furthermore, both P300 index and IVA-CPT had high accuracy and performance in identification of ADHDin, ADHDhi, and ADHDcom. However, for different subtypes of ADHD, no significant differences were observed of ROC curves between subgroups (P>0.05). In addition, the performance in IVA-CPT was positively correlated with the amplitude, and negatively correlated with the latency of P300.
conclusionThese results support the discriminant validity of P300 and IVA-CPT in distinguishing ADHD patients, providing a theoretical basis for P300 and IVA-CPT testing in the clinical diagnosis of ADHD.
