Initial report from the SAR-TRACK (SELNET) registry: a multicentric international retrospective analysis on the quality of the management of limb and trunk wall soft-tissue sarcomas (2012-2022) in Ibero-American countries.

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: Multidisciplinary (MDT) management of sarcoma patients, with adherence to clinical practice guidelines (CPG), has a positive impact on patients' outcomes. Sarcoma European & Latin-American Network (SELNET) is an international consortium aiming to improve sarcoma management in Ibero-America. This study presents data from the observational study Sar-Track, which assessed the adherence of SELNET institutions to CPGs. This study aimed to evaluate adherence to established quality indicators in the diagnostic and therapeutic management of patients with soft tissue sarcoma within the SELNET network. Methods: Data from sarcoma patients managed in SELNET institutions (2012-2022) were collected. The primary objective was to analyze the adherence to quality factors during diagnosis and treatment, comparing Ibero-American (IA) and Spanish (SP) institutions. Findings: Data from 1523 localized patients with sarcoma of limbs or trunk-wall were included in this analysis. The median age was 50 (28), with 780 (51%) being female in the whole series. Ethnicity data was not available. Patients managed in IA underwent fewer core biopsies [n = 138 (25%) vs n = 153 (57%), p < 0.0001], fewer magnetic resonance imaging (MRI) [n = 464 (59%) vs 500 (68%), p = 0.003], and fewer MDT discussions before surgery [n = 208 (27%) vs 737 (99.6%), p < 0.0001]. Surgical margin involvement occurred more often in IA cases [n = 215 (27%) vs n = 61 (9%), p < 0.0001], and less radiotherapy was administered in patients from IA [n = 172 (37%) vs n = 185 (62%), p < 0.0001]. Interpretation: This analysis establishes the baseline reality at the initial stage of SELNET, highlighting substantial opportunities for improving adherence to CPGs in Ibero-America. Funding: SELNET was supported by a European Horizon 2020 grant (H2020-SC1-BHC-2018-2020).
