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
backgroundGaming disorder (GD) is an emerging issue that leads to significant impairment, yet existing tools for measuring withdrawal symptoms in GD are limited and often fail to capture its multidimensional nature. Most current measures rely on single-item assessments or adapted tools from substance use disorders, overlooking cognitive, behavioral, and physiological components. A comprehensive, multidimensional questionnaire is needed to more accurately assess withdrawal in GD, aiding in early detection and intervention.
objectiveThe objective of this study was to develop and psychometrically validate a comprehensive measurement tool, the Gaming Withdrawal Symptoms Questionnaire (GWSQ), capturing the multidimensional nature of withdrawal symptoms in GD, including affective, cognitive, behavioral, and physiological components.
methodsA multistage psychometric approach was used, starting with item generation from a scoping literature review. Exploratory factor analysis and confirmatory factor analysis were conducted to refine the questionnaire. Reliability and validity were assessed using 2 cross-sectional studies. Data were collected anonymously via an online survey platform. Participants were recruited from gaming-related platforms and social media (eg, Discord, Reddit, and Facebook) and restricted to actively engaged adult gamers who passed attention check questions to ensure data quality.
resultsStudy 1 involved 480 adults (mean age 23, SD 4.96 years; n=327, 68.1% male). Study 2 included 565 adults (mean age 25, SD 5.55 years; n=245, 43% male). Exploratory factor analysis revealed a 3-factor model of withdrawal symptoms: (1) motivational and cognitive symptoms, (2) affective symptoms, and (3) physical symptoms, explaining 54% of the variance. Confirmatory factor analysis confirmed adequate model fit (χ
conclusionsThe GWSQ is the first validated multidimensional tool specifically designed to assess withdrawal symptoms in GD, representing a conceptual and methodological innovation. It addresses critical gaps in GD diagnosis and research by capturing a broader spectrum of symptoms beyond affective distress. The questionnaire's tripartite structure provides a framework for advancing theoretical models and informing etiological studies of GD. The GWSQ offers a robust measure for clinical research and enables differentiated assessment of symptom clusters. In real-world contexts, it can serve as a reliable patient-reported outcome tool in forthcoming clinical trials of GD interventions, enabling precise monitoring of treatment effects. Nevertheless, given the nonclinical sample, further cultural validation and studies involving clinical populations are required.
