Successful Palmar Arch Revascularization of Thromboangiitis Obliterans in the Upper Extremity.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThromboangiitis obliterans (TAO) is a nonatherosclerotic vasculitis predominantly affecting young male smokers, commonly involving arteries of the extremities.TAO in the upper extremity presents distinct clinical challenges because of its impact on functionality and the complexity of treatment. CASE SUMMARY: A 46-year-old man who was a heavy smoker presented with a 6 × 4 cm ulceration on the left hand. Peripheral angiography was performed to confirm the diagnosis and assess the arterial anatomy. After revascularization of radial and ulnar arteries and the palmar arch, blood flow was successfully restored through both the radial and ulnar arteries into the palmar arch. DISCUSSION: In this report, we describe a case successfully managed with complete upper extremity revascularization, highlighting the interventional strategy and its clinical outcomes. TAKE-HOME MESSAGES: TAO may affect the upper extremities, and there is no definitive treatment for upper extremity involvement. Percutaneous interventions and palmar arch angioplasty help prevent amputation and accelerate wound healing.
