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
introductionThe aim of the study was to examine differences in the occurrence of consequences of untreated dental caries (pulpal involvement, ulceration, fistula, and abscess-PUFA) across intersectional social positions defined by sex, skin color, and household income among adolescents.
methodsThis study analyzed data from the Brazilian National Oral Health Survey (SB Brasil 2023), using a multistage stratified probability sampling design to represent adolescents aged 15-19 years. Social variables were combined into 8 intersectional groups based on sex, skin color, and family income. Outcomes included PUFA prevalence ≥1 and counts of its components. Survey-adjusted Poisson regression with robust variance and a three-way interaction term was applied.
resultsThe sample comprised 4,892 adolescents. Compared to high-income White males, prevalence was higher among low-income Black males (PR = 5.93; 95% CI: 2.60-13.51) and low-income Black females (PR = 4.06; 95% CI: 1.85-8.90). The predicted prevalence of PUFA ≥1 ranged from 4.0% (95% CI: 2.0-7.0) among high-income White males to 21.0% (95% CI: 11.0-32.0) among low-income Black males. Among females, prevalence estimates were 15.0% (95% CI: 9.0-20.0) in high-income Black, 16.0% (95% CI: 5.0-28.0) in low-income White, and 18.0% (95% CI: 12.0-24.0) in low-income Black individuals.
conclusionMarked differences in PUFA occurrence were observed across intersectional social positions, with the highest burden observed among low-income Black adolescents, particularly males for prevalence ratios, although females also presented high absolute prevalence. These findings reinforce the need for policies addressing structural social inequalities in oral health.
