Evaluation of the Relationship Between the Grade of Lumbar Foraminal Spinal Stenosis and Outcomes of Dorsal Root Ganglion Pulsed Radiofrequency Treatment.

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
Objective: We aimed to evaluate the association between the radiological grade of lumbar foraminal spinal stenosis (LFSS) and the outcomes of dorsal root ganglion (DRG) pulsed radiofrequency (PRF) treatment. Materials and Methods: This is an observational, single-center study. Patients with LFSS who had undergone lumbar DRG-PRF treatment were evaluated according to the radiological grade of stenosis: Grades 1, 2, and 3. Severity of pain, presence of neuropathic pain, and functional status were assessed using a numerical rating scale (NRS), the Douleur Neuropathique en 4 (DN4) Questionnaire, and the Oswestry Disability Index (ODI) at baseline, first, and third months. The groups by grade consisted of 18, 22, and 23 patients, respectively, for Grades 1, 2, and 3. Results: NRS scores are similar at baseline and first month, but higher in Group 3 than in Groups 1 and 2 at the third month ( Conclusion: The DRG-PRF treatment is effective for pain and functional disability in LFSS in all grades, although pain scores remained higher in Grade 3 stenosis at the third month. Studies with larger sample sizes for each stenosis grade may provide more accurate and detailed information.
