Clinical predictors of treatment success following Gasserian ganglion conventional radiofrequency in trigeminal neuralgia: secondary cohort analysis.
Article in Journal of oral & facial pain and headache, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 study aimed to identify clinical predictors associated with treatment success following Gasserian ganglion conventional radiofrequency (CRF) in patients with trigeminal neuralgia (TN), with particular focus on the predictive value of early clinical response.
methodsThis retrospective secondary cohort analysis included 37 patients with classical TN who underwent Gasserian ganglion CRF at a tertiary pain clinic. Treatment success was defined as a ≥50% reduction in Numerical Rating Scale (NRS) score at 6 months compared with baseline. Demographic characteristics, baseline pain severity, trigeminal branch involvement, early post-procedural pain response, complications, additional treatment requirements, and patient satisfaction scores were analyzed. Receiver operating characteristic (ROC) analysis was performed to evaluate the predictive performance of early pain reduction for 6-month treatment success.
resultsTwenty-nine patients (78.4%) achieved treatment success at 6 months. The success group demonstrated significantly higher median age (67
conclusionsEarly post-procedural pain reduction appears to be a clinically useful marker of sustained mid-term treatment success after Gasserian ganglion CRF in TN. In particular, a ≥50% reduction in NRS score at 1 month may help identify patients likely to maintain meaningful pain relief at 6 months.
