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
backgroundThe inability to localize pain generators often results in failed back surgery syndrome (FBSS). Structural imaging can identify multiple and/or noncausative abnormalities. Molecular imaging of glucose transporters offers the opportunity to localize metabolically active sites. Using the radiotracer [18F]fluorodeoxyglucose (FDG) with positron emission tomography/magnetic resonance imaging (PET/MRI) has enabled the localization of malignant lesions and pain generators via regions of high inflammation. OBSERVATIONS: A 61-year-old woman was diagnosed with complex regional pain syndrome (CRPS) and experienced right greater than left upper-extremity pain. Following PET/MRI with the FDG radioligand for GLUT, increased radiotracer uptake was seen in the right C6 nerve root and dorsal root ganglion, providing additional information to the structural MRI findings of narrowing of the right C5-6 neural foramina. Together with pain relief following a transforaminal steroid injection to the area, these results prompted the authors to perform a C5-6 anterior cervical discectomy and fusion procedure, which resulted in significant symptom relief. LESSONS: The authors present a case of worsening upper-extremity CRPS with an occult radiculopathy that improved following surgery to address a pain generator identified by FDG PET/MRI. Localization of inflammatory sites can reduce FBSS and nonspecific management of pain believed to be resulting from spinal pain generators in a wide array of chronic pain syndromes. https://thejns.org/doi/10.3171/CASE24327.
