Spinal cord stimulation for atypical anterior chest wall complex regional pain syndrome: illustrative case.
Article in Journal of neurosurgery. Case lessons, 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
backgroundComplex regional pain syndrome (CRPS) most commonly affects distal extremities; atypical truncal presentations may be underrecognized and can mimic cardiopulmonary pathology. OBSERVATIONS: A 27-year-old male developed chronic, severe anterior chest wall pain characterized by marked tactile allodynia, episodic erythema, and environmental trigger sensitivity. An extensive multidisciplinary evaluation excluded cardiopulmonary, gastrointestinal, dermatological, infectious, and structural etiologies. The clinical phenotype met Budapest criteria for CRPS type I, including disproportionate pain, symptoms across multiple domains, and objective signs on examination, without an alternative diagnosis better explaining the presentation. Symptoms were refractory to multimodal therapy, prompting a spinal cord stimulation (SCS) trial followed by permanent implantation after significant trial benefit. The patient experienced sustained analgesia and functional improvement at 3, 12, and 24 months, with only minor stimulation-related limitations. LESSONS: This case demonstrates that CRPS may present in an atypical anterior chest wall distribution. Explicit Budapes criteria documentation and a reproducible exclusionary workup strengthen diagnostic confidence. SCS may provide durable relief for refractory atypical CRPS phenotypes. https://thejns.org/doi/10.3171/CASE26152.
