Investigating the Effects of Pulsed Radiofrequency on Dorsal Root Ganglion in Chronic Lumbar Radicular Pain Patients: Is It Not Important that We Ask the Right Question, the Right Way, on an Appropriate Sample of Patients?
Bibliographic record
Abstract
Dear Editor, It is interesting to read the paper by Koh et al. on the investigation of the pulsed radiofrequency (PRF) of the dorsal root ganglion (DRG) in patients of chronic lumbosacral radicular (CLR) pain [1]. It is noteworthy that the authors attempted to perform a controlled trial on a challenging topic. However, I am afraid that the study design, results, and conclusions have further “muddied the water” instead of bringing clarity to the existing evidence on the efficacy of PRF-DRG in CLR pain patients. I would like to highlight some aspects of the study, which decrease the confidence in their study results and conclusions. The study was conducted on patients of lumbar spinal stenosis (LSS). Note that LSS is a radiological diagnosis, and the clinical diagnosis of spinal stenosis and its symptoms (leg pain) bear no relation to the extent of corresponding imaging findings of either central or foraminal stenosis. However, generally patients with central stenosis present with neurogenic claudication, whereas lateral foraminal stenosis could cause symptoms similar to radicular elements of …

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
