Dermatologic manifestations of complex regional pain syndrome improved after dorsal root ganglion stimulation.

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
Background: Complex regional pain syndrome is a condition that causes autonomic dysfunction, including severe pain, swelling, temperature fluctuations, and cutaneous flushing. Case Description: The patient was a 38-year-old woman with complex regional pain syndrome type I of the right foot that developed after a work-related accident. At the time of presentation, she complained of a stabbing and burning pain, which subjectively felt like extreme warmth for 6 weeks. On physical examination, she presented with diffuse cutaneous flushing, erythema, nonpitting edema, skin mottling of the medial aspect of the right foot and ankle, a purple macule on the right inferomedial aspect of the great toe, and a purple patch on the inferomedial aspect of the heel. The patient underwent right-sided L5/S1 open dorsal root ganglion (DRG) stimulation under the care of neurological surgery. Postprocedurally, the cutaneous flushing, erythema, edema, mottling, purple macule, and patch had completely resolved. At the 1-year postoperative appointment, the patient continued to have a significant improvement in her preoperative pain and notably improved allodynia, flushing, mottling, and temperature sensitivity. Conclusion: We have described the successful resolution of complex regional pain syndrome associated dermatologic manifestations in the setting of DRG stimulation. To our knowledge, a case of this nature has yet to be described in the literature.
