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
Aim: Significant, positive correlations between internet gaming disorder (IGD) and autism spectrum disorder (ASD) are known. Individuals with ASD are prone to problematic internet use due to addiction or restricted interests. Here, we examined cortical neural activity in individuals with IGD comorbid with ASD during a gaming-related cue reactivity task, using magnetoencephalography (MEG). Methods: MEG was used to record neural activity in right-handed male participants aged 11-20 years (11 IGD-ASD, 13 healthy controls; intelligence quotient [IQ] ≥ 80). IGD and ASD were diagnosed per DSM-5-TR criteria. During MEG recording, participants viewed gaming cues and neutral base stimuli in a cue reactivity task. Source-level cortical activity was estimated using minimum norm estimation (MNE), and statistical comparisons were performed using two-tailed nonparametric permutation tests with false discovery rate (FDR) correction. Results: In the IGD-ASD group, neural activity was significantly elevated at 137 ms in the right fusiform gyrus during gaming cues compared with the base condition ( Conclusion: The IGD-ASD group showed increased right frontal activity and decreased left occipital, fusiform, lingual, and parahippocampal activity during exposure to the gaming cue, suggesting atypical visual and cognitive processing mechanisms in this comorbid group. Further studies comparing individuals with ASD and those with IGD-ASD, as well as by examining the neurophysiological characteristics of individuals with ASD who develop or recover from IGD, might clarify the pathology of these populations.
