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
Malocclusions in primary teeth affect chewing, speech, and aesthetics. Few studies have assessed their impact on preschoolers' self-reported quality of life. This study aims to determine the association between malocclusions in primary teeth and preschoolers' quality of life based on reports from children and their parents/guardians. A cross-sectional study was conducted Using a stratified, simple, randomly probabilistic sample. Based on sample size estimation, the study included 566 five-year-old preschoolers and their parents/guardians from Teresina, Brazil. Pediatric Quality of Life InventoryTM questionnaire and sociodemographic forms were applied, and clinical examination was performed. The dmft index, modified developmental defects of enamel, and Foster & Hamilton criteria were used for diagnosis. Descriptive analysis and Poisson regression were performed (p < 0.05; 95% CI). Prevalence of malocclusion was 51.2%. Parents/guardians reported edge-to-edge overjet negatively affected physical capacity (RR = 1.11; 95%CI: 1.02-1.20) and social aspects (RR = 1.11; 95%CI: 1.03-1.19). According to children's self-reports, posterior crossbite affected the total score (RR = 1.43; 95%CI: 1.03-1.97) and oral health (RR = 1.08; 95%CI: 1 .04-1.13), whereas reduced overbite was linked to negative effects on the emotional aspect (RR = 1.10; 95%CI: 1.01-1.18) and oral health (RR = 1.08; 95%CI: 1.01-1.16). Malocclusions have a negative impact on the quality of life of preschoolers, as reported by parents and children.
