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 aim of the study was to assess the validity, reproducibility, and reliability of the Brazilian version of the smartphone addiction scale in children.
methodsThe sample included 194 children (105 girls), aged 8-10 years, enrolled in the public school system of the city of Curitiba (PR). A self-reported questionnaire assessed sociodemographic data (sex, age, type of housing, type of residence, number of siblings, and father's and mother's education). The ABEP (Associação Brasileira de Empresas de Pesquisa) questionnaire assessed economic class, and the Smartphone Addiction Scale-Short Version assessed problematic smartphone use (PSU). Factor analysis was performed to analyze the validity of the PSU scale; the intraclass correlation coefficient (ICC) was used to assess the reproducibility of the instrument; and reliability was measured by internal consistency using Cronbach's alpha (α). All analyses were performed using SPSS (Statistical Package for the Social Sciences) version 21.0 software, adopting a significance level of p<0.05.
resultsFactor analysis resulted in three factors that explained 50.2% of the total variance. The ICC ranged from 0.34 to 0.81, with a value of 0.85 as the overall score. Cronbach's α ranged from 0.35 to 0.81, with an overall score of 0.87.
conclusionsThe scale showed adequate factorial validity and acceptable consistency and reproducibility. The use of this scale is recommended in studies conducted with children aged 8-10 years.
