Socioeconomic Status and Survival in Sarcomas of the Breast: Nationwide Cohort Study.

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
introductionSocioeconomic status (SES) has been associated with survival in breast cancer; yet its role in sarcomas of the breast remains poorly studied. We aimed to investigate whether individual-level SES, approximated by educational attainment and household income, is associated with overall survival in a nationwide cohort of women with sarcomas of the breast within a universal healthcare system.
methodsWe conducted a nationwide cohort study by using linked Swedish population registers. Women diagnosed with an incident borderline or malignant phyllodes tumor (PT), angiosarcoma, or soft-tissue sarcoma of the breast from 1993 to 2018 were included and followed through 2019. Socioeconomic status was defined by highest attained education and household disposable income. The primary outcome was all-cause death. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated by using multivariable Cox proportional hazards regression.
resultsA total of 473 women were included (median age, 51 years). The cohort comprised 198 borderline PT, 179 malignant PT, 25 angiosarcomas, and 71 soft-tissue sarcomas. Median follow-up was 13.1 years. In multivariable analyses, educational level was not associated with overall survival (OS) (≤9 vs. >13 years, HR 1.29, 95% confidence interval [CI] 0.76-a2.22; 10-13 vs. >13 years, HR 1.16, 95% CI, 0.71-1.89]). Lower household income was associated with worse OS (Q1 vs. Q5, HR 2.35, 95% CI 1.22-4.52; Q2 vs. Q5, HR 1.98, 95% CI 1.06-3.7).
conclusionsLower income, but not education level, was associated with worse OS in patients with sarcomas of the breast. These results underscore the presence of survival disparities among patients with rare breast tumors, even within a universal healthcare system.
