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 Peripheral artery disease (PAD) affects many individuals in the United States and imposes substantial healthcare costs. Chronic limb-threatening ischemia (CLTI) is a severe form of PAD. This study evaluates racial disparities in access to different treatment approaches for CLTI, hypothesizing that patients of Black self-reported race may experience significant barriers to receiving open surgical bypass. Methods In this retrospective study, data were analyzed from the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database. All recorded cases of surgical bypass, endovascular revascularization, or amputation below the knee for the treatment of CLTI from 2012 to 2021 were included in this analysis. Propensity score matching and univariate analyses were conducted to evaluate the association between self-identified race, treatment access, and clinical outcomes. Results A total of 42,889 cases of CLTI were identified. Black patients were less likely to undergo open surgery (5,000 (38.4%) vs. 13,981 (47.7%); p < 0.001) and more likely to undergo endovascular therapy (6,402 (49.2%) vs. 13,299 (45.3%); p < 0.001) and amputation (1,621 (12.4%) vs. 2,060 (7.0%); p < 0.001). Black patients also experienced higher rates of postoperative complications, including cardiac arrest, deep vein thrombosis, sepsis, myocardial infarction, ventilator dependence >48 hours, reoperation, 30-day mortality, and 30-day readmission. After propensity score matching and logistic regression, Black self-reported race remained an independent predictor of endovascular revascularization and amputation rather than open bypass. Conclusions This study revealed a significant racial disparity in access to open bypass among self-identified Black CLTI patients. Patients of Black self-reported race were more likely to experience postoperative complications or reoperation within 30 days following the operation. Although an endovascular technique may reduce 30-day complications, recent literature indicates that open bypass may improve long-term postoperative outcomes. These results highlight the need for further investigation to identify and mitigate barriers contributing to disparities.
