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
Introduction: Acute lower limb ischemia (ALI) is a life and limb threatening event often affecting patients with type 2 diabetes mellitus (T2DM). Little is known about how T2DM affects the risk of adverse events in patients revascularized for ALI. This study aimed to investigate if there were differences in major outcomes between ALI patients with and without T2DM. Methods: Between 2010 and 2014, 615 patients underwent revascularization for ALI, according to the Swedish Vascular Registry (SWEDVASC). Using the National Diabetes Registry (NDR), 245 (39.8%) of the patients were identified as having T2DM. Uni- and multivariable Cox or logistic regression analyses were performed to evaluate risk differences for major amputation, mortality, major adverse cardiovascular events (MACE), and fasciotomy between patients with and without T2DM. Results: The rates of major amputation and mortality at one year were 32.7% and 21.6% in the T2DM group, compared to 21.9% and 31.9% in the non-DM group, respectively, resulting in a hazard ratio (HR) of 1.52 (95% confidence interval [CI] 1.12-2.07) for major amputation and HR of 0.64 (95% CI 0.46-0.88) for mortality. At one year, the HR for major amputation was 1.45 (95% CI 0.99-2.11), HR for mortality 0.92 (95% CI 0.61-1.39), HR for combined major amputation/mortality 1.27 (95% CI 0.94-1.72), and HR for MACE 1.24 (95% CI 0.92-1.67) for those with T2DM compared to those without in the multivariable Cox-regression analyses. The multivariable logistic regression analysis showed significantly lower odds of fasciotomy, OR 0.1 (95% CI 0.01-0.51) in the T2DM-group. Conclusion: T2DM was not significantly associated with higher hazard of major amputation, mortality, combined major amputation/mortality, or MACE after revascularization for ALI, compared to patients without T2DM. Patients with T2DM had significantly lower odds of fasciotomy.
