1 · What the graph read from it

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.

2 · The registry

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

backgroundAlthough microvascular decompression (MVD) is recognized as the preferred therapy for drug-resistant idiopathic glossopharyngeal neuralgia (GPN), the management of recurrent GPN following MVD is seldom mentioned in the current literature. This study aims to demonstrate the efficacy and safety of salvage Gamma Knife surgery (GKS) in the treatment of recurrent GPN after MVD.

methodsFrom October 2012 to January 2018, seven patients (three males and four females) underwent salvage GKS for recurrent GPN following MVD, including two patients who received repeat GKS due to pain recurrence after their initial GKS salvage. The median age was 69 years (range 49-81 years) at first GKS and 72 years (67 years; 77 years) at second GKS. The delivered dose was 80 or 90 Gy at first GKS and 90 Gy at second GKS. Pain outcome was assessed according to the Barrow Neurological Institute (BNI) score.

resultsThe median duration of follow-up after first GKS was 68 months (range 29-89 months) and 45 months (56 months; 33 months) after second GKS. The median time to pain response was 24 days (range, 6-80 days). One patient experienced palatoglossal hyperesthesia after first GKS, and no complications were noted after second GKS. At the last follow-up, 4 patients were BNI I, 1 was BNI II, and 2 was BNI IIIa.

conclusionsSalvage GKS is safe and effective for treating recurrent GPN after MVD, even for patients who experienced pain recurrence following their initial GKS salvage.
