Incidence and trends of multiple myeloma (MM) in Brazil - 1988-2020.
Article in Ecancermedicalscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Multiple myeloma (MM) is a chronic hematological malignancy caused by a differentiated plasma cell disorder (Pawlyn, 2019). As a consequence of population aging, there has been an increase in incidence rates (Turesson Objective: To analyse the incidence rates and trends of MM across states in Brazil from Population-Based Cancer Registries (PBCRs). Methodology: Information was extracted from PBCR/INCA for the 1988-2020 period. Sociodemographic data were extracted from records of the Brazilian Institute of Geography and Statistics. Age-standardised incidence rates were calculated using the Segi global standard population. Trend analysis was performed using Join point Regression, version 4.7.0.0. Results: The highest incidence rates of MM in males were observed in the cities of Natal (Rio Grande do Norte state) and Jaú (São Paulo state) at 3.55/100,000 and 2.9/100,000, respectively. In females, rates were highest in the cities of Natal (Rio Grande do Norte state) and Aracajú (Sergipe state) at 2.66/100,000 and 2.21/100,000, respectively. Trends showed an annual increase of 10.45% in Campinas for males and 9.04% for females. Median age at diagnosis in Brazil was 65 years for both sexes, while the North region had the lowest average age at 63.2 years, and the South region the highest at 68.0 years. Porto Alegre city (Rio Grande do Sul state) had the highest average of 70.0 years for females and 67.1 for males, while Roraima had the lowest at 61.2 years for females and 54.2 for males. Conclusion: In Brazil, the average age of incidence varies by geographic region, but is higher among males. Incidence rates are highest in the Northeast and Southeast regions, whereas the greatest upward trends are in the Southeast and Midwest regions.
