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 objective of this study was to evaluate the psychometric quality of the Game Addiction Scale for Adolescents (GASA shortened version) in its adapted version for Mexican children.
methodsThe instrument was administered to 289 primary school students using a non-probability quota sampling method. The average age of the participants was 10.47 years, with a standard deviation of 1.003 years, with 55% being boys and 45% being girls. Descriptive statistics were obtained from the seven items which make(made) up the scale to proceed with the confirmatory factor analysis (CFA), which was carried out using the robust estimation method Satorra-Bentler and the fit indices RMSEA (Root-mean square error of approximation), CFI (Comparative fit index), and SRMR (Standardized root mean square residual), as well as the X2/df ratio. Likewise Nevertheless, an analysis of the invariance of the factorial structure according to the sex of the participants was performed. Finally, reliability was determined by subscales using the McDonald's omega coefficient.
resultsThe CFA shows a good adjustment data for the uni-factorial proposed model (X
