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
objectiveTo identify the associated factors to loneliness among Brazilian adolescents, considering this is a knowledge gap and given its severity. The United Nations estimates that mental health problems affect approximately 20% of adolescents worldwide.
methodsThis is a cross-sectional study with data from the National Adolescent School-based Health Survey 2015, conducted with students aged 13-17 in Brazil. The statistical analysis was performed with the calculation of the prevalence of feeling loneliness reported. Poisson regression with the adjusted Prevalence Ratio was used to evaluate the association between sociodemographic characteristics, family context, mental health and lifestyles, and feelings of loneliness.
results15,5% of Brazilian students reported loneliness in the last 12 months. Female gender, higher maternal education, insomnia and be bullying victims rarely or sometimes and most of the time or always had a higher prevalence rate of loneliness. Having friends, having a meal with parents or guardians 5 days or more a week and having understanding parents showed a lower prevalence ratio for loneliness.
conclusionLoneliness feeling is frequent among adolescents and is associated with female gender, less social and family support, intra-family violence and risk behaviors such as alcohol consumption and bullying. Policies to promote physical and mental well-being in this age group, stimulating friendship and family participation in the lives of adolescents should be made .
