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 analyze regional disparities in time-to-treatment initiation and initial therapeutic modalities adopted for malignant melanoma of the skin in Brazil between 2013 and 2023.
methodThis is a cross-sectional study based on secondary data extracted from the Oncology Panel. Prevalence ratios and 95% confidence intervals for time-to-treatment initiation were estimated by treatment region and initial therapeutic modality using Poisson regression with robust variance.
resultsA total of 23,145 records were analyzed. Surgery was the main initial therapeutic modality in all regions, with 89.0% of procedures performed within 30 days of diagnosis, especially in the Southern region (88.6%). In contrast, chemotherapy and radiotherapy were predominantly initiated after 60 days, with the highest percentages in the Northern region (56.1% and 77.4%).
conclusionSignificant disparities in time-to-treatment initiation were observed between the Brazilian regions, regardless of therapeutic modality, except in the Midwest region regarding radiotherapy. The findings highlighted the need for actions to promote greater equity in access to cancer treatment, in accordance with Law No. 12732/2012, aiming to improve clinical outcomes for users.
