Abstract
INTRODUCTION: There is a lack of evidence to guide the choice between stereotactic radiosurgery (SRS) and neuroablative procedures for patients with medically refractory trigeminal neuralgia (TN). This meta-analysis aims to identify the outcomes of these interventions for TN. METHODS: Studies identified through PubMed, MEDLINE, and Embase, were cohort studies or clinical trials, had ≥20 participants, and had a ≥12-month follow-up. All participants were ≥16 years old and had primary refractory TN. Studies reported outcomes using the Barrow Neurological Institute (BNI) scale. The Shapiro-Wilk test, Mann-Whitney U test, two-tailed T Test, Spearman's R, and ANCOVA were used to test statistical significance. Screening was done according to PRISMA guidelines. Bias assessment was according to the Newcastle-Ottawa Scale. RESULTS: 3,288 patients from 37 studies were included (2,537 SRS, 751 neuroablative). Overall reporting of BNI I, II, III, IV, and V was 36.0%, 17.4%, 23.9%, 11.7%, and 10.9%, respectively, in the SRS cohort, and 63.6%, 10.4%, 11.1%, 7.3%, and 7.6%, respectively, in the neuroablative cohort (p < 0.0001). Recurrence was 41.6% in the SRS cohort and 22.5% in the neuroablative cohort (p < 0.001). The neuroablative cohort reported significantly higher rates of hypoesthesia (18.6% vs. 50.5%, p < 0.0001), and minor (19.6% vs. 2.2%, p < 0.0001) and major (3.4% vs. 1.3%, p < 0.001) adverse effects compared to SRS. CONCLUSION: The findings suggest improved pain relief and reduced recurrence with neuroablative procedures compared to SRS, albeit conferring a higher rate of adverse effects. Neuroablative techniques may be more appropriate for patients with medically refractory TN who are unsuitable for microvascular decompression.

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 it
