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 investigate association between the sociodemographic profiles of individuals with oral cancer in Brazil and the time interval between diagnosis and initiation of treatment.
methodsThis was a cross-sectional study of reported oral cancer cases in Brazil from 2011 to 2020, using data from the Cancer Hospital Registry Information System of the Brazilian National Cancer Institute (Sis-RHC/INCA). Sociodemographic profiles were identified using two-step cluster analysis, and associations were estimated using multinomial logistic regression, with odds ratios (OR) and 95% confidence intervals (95%CI).
resultsThe sample included 25,169 cases diagnosed between 2011 and 2020, which defined four distinct profiles: A) married men aged 40-79, White, with less than 8 years of schooling, from the Southern region; B) married men aged 40-79, Black, with 8 years of schooling, from the Northeast region; C) married men aged 40-79, Black, with less than 8 years of schooling, from the Northeast region; D) widowed women aged 40-79, Black, with less than 8 years of schooling, from the Southeast region. Compared to profile D, profile A showed 61.5% lower odds of starting treatment ≥91 days after diagnosis (OR 0.38; 95%CI 0.26; 0.55), profile B showed 50.0% lower odds (OR 0.50; 95%CI 0.32; 0.77), and profile C showed 35.4% lower odds (OR 0.64; 95%CI 0.45; 0.92).
conclusionSignificant differences exist in the time to treatment initiation for oral cancer across distinct sociodemographic groups.
