Radiation-Induced Subclavian Artery Stenosis With Varying Lesion Complexity Requiring Revascularization.
Article in JACC. Case reports, 2026. 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
backgroundRadiation-induced atherosclerosis represents an underestimated clinical entity. CASE SUMMARY: We report on 2 cases of patients with upper-limb ischemia due to subclavian artery lesions. Both patients had radiation therapy due to cancer more than 15 years before symptom onset and no other signs of atherosclerosis. Angiography and intravascular ultrasound were performed in both cases, and lesions were treated with angioplasty and stent placement in the first patient, whereas intravascular lithotripsy was necessary in the second patient due to severe calcification and balloon underexpansion. DISCUSSION & TAKE-HOME MESSAGES: Intravascular ultrasound helps to accurately assess lesion characteristics, size the balloon and stent devices, and judge the effectiveness of the endovascular therapy. Since radiotherapy is linked to accelerated atherosclerosis, such patients may benefit from clinical and imaging surveillance by duplex ultrasound.
