Review in Pain practice : the official journal of World Institute of Pain, 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
introductionDespite advancements in pharmacological and intrathecal treatment of oncological pain, it remains a significant challenge, affecting 44.5% of patients with cancer, with 30.6% experiencing moderate-to-severe pain.
methodsThis scoping review provides a summary of the literature from 2016 to 2024, focusing on percutaneous cordotomy techniques and clinical outcomes for the treatment of unilateral pain in patients with cancer. A literature search (in Medline and Embase) was performed from inception up to September 9, 2024, in collaboration with a medical information specialist.
resultsA comprehensive multidimensional assessment is essential when considering cordotomy. Ideal candidates have unilateral pain unresponsive to more conservative measures, localized below the C4 level. A detailed neurological examination is crucial for intra-procedural assessment and to evaluate potential post-procedural muscle weakness and sensory deficits. Our search identified 18 studies, half of which were retrospective and half prospective, including 596 patients in total. Studies varied regarding imaging technique and included fluoroscopy, CT-guided, or via microendoscopy. Excellent immediate pain relief was reported in between 86% and 98% of patients. Of patients surviving 6 months, the majority still experienced sustained pain relief. There is no consensus regarding optimal lesion temperature and duration. The reported rate of permanent complications such as paresis is low. The reported incidence of mirror pain is highly variable.
conclusionsCancer pain should ideally be managed in a multidisciplinary and multimodal manner. When conservative treatment fails, a percutaneous cordotomy can be considered for refractory unilateral pain.
