Prostate Cancer Disparities in Clinical Characteristics and Survival among Black and Latino Patients Considering Nativity: Findings from the California Cancer Registry.

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
backgroundWe investigated clinical characteristics and prostate cancer survival patterns among Latino patients considering nativity compared with non-Latino Black (NLB) and non-Latino White (NLW) patients.
methodsWe used data from the California Cancer Registry (1995-2021), which included 347,540 NLW, 50,032 NLB, and 75,238 Latino patients with prostate cancer. Frequencies of sociodemographic and clinical variables were assessed using χ2 tests. Multivariable regression models were fitted to evaluate determinants of treatment reception, Gleason upgrade, and survival differences. Exploratory analyses were conducted grouping Latino cases into US born and non-US born by country of origin.
resultsCompared with NLW, NLB cases had the greatest proportion of younger patients, whereas non-US-born Latino patients had the greatest proportion of low socioeconomic status and uninsured patients. Non-US-born Latinos showed a greater proportion of diagnoses completed with <6 core biopsies, Gleason >8, stage IV tumors, and metastasis. Multivariable analyses showed that compared with NLW, Latino patients were as likely to receive treatment, whereas NLB cases were less likely (OR = 0.81; 95% confidence interval, 0.67-0.98; P = 0.029). Compared with NLW, non-US-born Latino cases were less likely to die of prostate cancer (HR = 0.78; 95% confidence interval, 0.64-0.94; P = 0.011), with no difference reported for NLB cases.
conclusionsConsidering sociodemographic and clinical characteristics, non-US-born Latino patients with prostate cancer had better survival than NLW. This highlights the need to identify key determinants of these survival differences and the importance of sociodemographic and clinical determinants in survival disparities. IMPACT: Our study emphasizes the importance of considering nativity among Latino patients to understand prostate cancer disparities and outcomes in this population.
