Particulate and Non-Particulate Steroids in Lumbar Transforaminal Epidural Injections
Bibliographic record
Abstract
Dear Editor, We welcome the efforts of El-Yahchouchi et al. [1] on undertaking a retrospective study of a large patient cohort to address the important issue of comparison of efficacy of particulate (triamcinolone and betamethasone) and nonparticulate (dexamethasone) lumbar transforaminal epidural steroid injections (TFESI). The authors conclude that lumbar TFESI of dexamethasone is noninferior to betamethasone and triamcinolone for treatment of radicular pain and that dexamethasone is superior to triamcinolone and betamethasone with regard to pain and functional outcome at 2 months. However, we have several questions regarding their methodology and conclusions of this article. First, particulate steroids were used in 87% (N = 3,162) of their TFESIs, whereas dexamethasone was used in only 13% (N = 481). This is a considerable difference in sample size between the particulate and nonparticulate groups, and it is reflected in the wider …

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.
