Case Report: Cryoanalgesia for intractable thoracic pain due to chest wall tumor.
Article in Frontiers in oncology, 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
Introduction: Postoperative pain in thoracic surgery is a major concern, often delaying recovery. Cryoanalgesia, using pressurized nitrous oxide, offers long-term pain relief by temporarily blocking peripheral nerve function. It takes effect within 72 hours, so an intercostal nerve block is used for immediate pain relief. Cryoanalgesia is effective for severe pain, with minimal side effects and no drug interactions. Case report: A 63-year-old man with severe thoracic pain, unresponsive to opioids, was diagnosed with a typical carcinoid tumor after a CT scan revealed lesions in his lung, thoracic wall, and adrenal gland. He underwent surgery for the thoracic lesions with cryoanalgesia, leading to excellent recovery and no pain. A month later, the adrenal lesion was removed laparoscopically. He remains pain-free and free of recurrence after one year, indicating successful treatment. Conclusion: Cryoanalgesia provides long-term relief for chest pain caused by tumors, with minimal side effects. It improves recovery and should be considered an essential part of pain management in thoracic surgery.
