Clinical Outcomes after Revascularization in Patients with Chronic Limb-Threatening Ischemia.
Review in Annals of vascular diseases, 2025. 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
Chronic limb-threatening ischemia (CLTI) occurs in the advanced stage of peripheral artery disease and is associated with high risks of mortality and amputation. Universal management strategies are not always applicable, owing to population diversity, and the Western trials may not be applicable to Japanese patients, owing to differences in demographics and clinical profiles. This paper examines the outcomes of revascularization in Japanese CLTI patients and emphasizes the benefits of tailored management. Post-hoc analysis of the bypass versus angioplasty in severe ischemia of the leg (BASIL)-1 trial validated the use of the Global Limb Anatomic Staging System for predicting the outcomes of endovascular therapy (EVT) but not bypass surgery (BS). The SPINACH (surgical reconstruction versus peripheral intervention in patients with critical limb ischemia) registry revealed comparable 3-year amputation-free survival rates between patients who underwent EVT and those who underwent BS, with patient-specific factors such as limb status and general health influencing its success. Revascularization improved the quality of life, but benefits declined over time, especially in non-ambulatory and older patients on dialysis. Surgical reconstruction is better for preserving ambulation. Retrospective studies revealed pedal branch artery bypass as a viable option, functional independence as a predictor of survival, and zinc supplementation as promising for wound healing. Future research should focus on refining these strategies and exploring innovative approaches to overcome persistent challenges in CLTI care.
