From Leksell's Arc to El Salvador: The Thalamotomy of Pain and the Global Democratization of Functional Radiosurgery.
Article in Cureus, 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
Lars Leksell's pioneering vision of bloodless neurosurgery through radiosurgical precision revolutionized functional neurosurgery. This editorial revisits the historical and philosophical roots of radiosurgical thalamotomy for pain and explores its modern revival in low- and middle-income countries (LMICs), specifically in El Salvador. The integration of artificial intelligence (AI), connectomic targeting, and non-ablative dosing has redefined the possibilities of functional radiosurgery beyond traditional centers of innovation. At the Centro Internacional de Cáncer, we have implemented a wide range of radiosurgical targeting strategies, including sub-necrotic 90 Gy treatments to the thalamus and hypophysis for pain control. This experience highlights both the versatility of precision radiosurgery and its feasibility within resource-constrained environments. This article argues that the next frontier of functional neurosurgery lies not only in technical innovation but also in the ethical and global democratization of access. Were Leksell alive today, he would find his prophecy fulfilled in the convergence of data-driven precision and humanitarian purpose.
