Socioeconomic disparities in sarcoma diagnosis, expert center access, and advocacy group awareness: a multicenter study in Southern Europe.
Article in The oncologist, 2026. 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
backgroundManagement of sarcoma in expert centers (SECs) improves outcomes, and patient advocacy groups provide information, support, and representation of patients' needs; however, access to both remains uneven. We aimed to identify factors associated with patient referral and advocacy group awareness in Spain and Portugal, 2 universal healthcare systems with distinct sarcoma pathways. MATERIALS AND
methodsBetween April and December 2023, we conducted a survey-based study of adults with sarcoma under active treatment or follow-up across 9 Spanish hospitals (5 SECs) and one Portuguese hospital. Sociodemographic and clinical data, referral patterns, and advocacy group awareness/contact were analyzed.
resultsA total of 415 patients were included (Spain, n = 365; Portugal, n = 50). In Spain, lower income (odds ratio [OR] 2.38; 95% CI, 1.16-5.03) was associated with longer diagnostic delays. Rural residence (OR 3.48; 1.79-7.04) and longer diagnostic delays (OR 2.41; 1.26-4.66) were associated with referral to other hospitals. Cancer advocacy group awareness was lower among patients with lower income (OR 0.38; 0.17-0.81) and higher with longer diagnostic delays (OR 2.08; 1.05-4.25). Sarcoma-specific advocacy group awareness was generally low (20%) but higher with university education (OR 4.27; 1.56-12.35). Few patients contacted cancer (14%) or sarcoma-specific groups (7%); contact was more frequent with longer diagnostic delays (OR 2.27; 1.11-4.63) or symptomatic presentation (OR 2.50; 1.04-5.97). Compared with the Portuguese cohort, Spanish patients were referred less frequently and had greater awareness of advocacy groups.
conclusionSocioeconomic disparities affect sarcoma diagnosis, referral, and advocacy group engagement, even within universal healthcare systems. Equity-oriented care requires timely SEC referral and advocacy group visibility.
