Combined bidirectional spinal cord stimulation for refractory neuropathic pelvic pain: a case report.
Article in Frontiers in pain research (Lausanne, Switzerland), 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
Introduction: Refractory neuropathic pelvic pain significantly impairs quality of life and is notoriously difficult to treat. We present the case of a 63-year-old woman who developed severe pelvic pain following emergency open thoracic aortic aneurysm repair. Despite extensive pharmacologic, non-pharmacologic, and interventional treatments, she experienced minimal relief. Methods: To address her pain, we attempted a novel approach termed "Combined Bidirectional": anterograde (thoracic) and retrograde (sacral) spinal cord stimulator (SCS) placement, accompanied by combination therapy-high-frequency stimulation (HFX) at the thoracic spine and tonic stimulation at the sacral spine. Case description: Technical difficulties complicated retrograde sacral placement, and we discussed our approach to managing these challenges. Additionally, the patient developed unexpected hip pain with tonic sacral stimulation, prompting discontinuation of this modality and continuation of HFX thoracic stimulation alone. Conclusion: This case underscores both the potential advantages and challenges of combined bidirectional SCS for pelvic pain. Further research is warranted to clarify the efficacy and optimal application of this novel approach for refractory neuropathic pelvic pain.
