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 assess the knowledge and practices of adolescents attending state public schools in Curitiba, Paraná, regarding hepatitis A.
methodsA cross-sectional study evaluating the knowledge and practices of adolescents aged 16 years or older, recruited by convenience sampling from public schools in Curitiba, Paraná. Knowledge was assessed using multiple-choice questions, organized into three dimensions: Pathology; Transmission and Symptomatology; and Prevention and Cure. Risk behaviors were scored in ascending order of exposure and grouped into five dimensions: Hygiene; Dietary Habits; Drinking Water; Tobacco Products; and Sexual Behaviors. Scores were standardized on a 0-10 scale and classified as very low (0⊢2.5), low (2.5⊢5), moderate (5⊢7.5), and high (7.5⊢10). Appropriate descriptive and inferential analyses were performed.
resultsA total of 298 adolescents participated (52.0% female; 63.1% self-identified as White), with a mean age of 16.6±0.7 years. The mean knowledge score was 3.7±3.0 and was higher among females (p=0.039). The lowest mean score was observed in the Transmission and Symptomatology dimension (3.3±3.2; p<0.001). The mean risk behaviors score was 1.7±1.3 and was higher among males (p=0.001); higher scores indicate greater exposure to risk behaviors. The Sexual Behaviors dimension presented the highest score (6.3±1.4; p<0.001). No correlation was found between knowledge and risk behaviors (Spearman's rho=0.00; p=0.983).
conclusionKnowledge about hepatitis A was low, particularly regarding transmission and symptoms. Although the overall risk behaviors score fell within the low category, the Sexual Behaviors dimension was classified as moderate, indicating a relevant vulnerability that requires targeted interventions for adolescents.
