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
introductionHerpes zoster is an acute condition caused by the reactivation of varicella zoster virus, often affecting the skin and mucosa. When varicella zoster virus invades the trigeminal ganglion, it can lead to trigeminal herpes zoster, with postherpetic neuralgia as the most common complication. Postherpetic neuralgia, characterized by persistent pain for over 3 months after skin lesions heal, significantly impacts quality of life, including sleep, mood, and social interactions. Current treatments, including antiviral drugs, analgesics, and neurotrophic agents, are often insufficient, and many patients still suffer from refractory postherpetic neuralgia. This highlights the need for alternative treatments. Trigeminal ganglion electrical stimulation has shown potential in managing refractory trigeminal herpes zoster and preventing postherpetic neuralgia. However, reports on its effectiveness remain scarce. This article presents two rare cases where trigeminal ganglion electrical stimulation was successfully used to treat refractory trigeminal herpes zoster and prevent postherpetic neuralgia. CASE PRESENTATION: This study reports two cases of trigeminal herpes zoster that were refractory to pharmacological treatment and successfully alleviated using trigeminal ganglion electrical stimulation, which also effectively prevented postherpetic neuralgia. Both patients, a 62-year-old Chinese female and a 65-year-old Chinese male, presented with severe pain, itching, sensory disturbances, and extensive vesicular lesions on the left side of the face, involving the ophthalmic (V1) and maxillary (V2) branches. Despite receiving antiviral drugs, analgesics, and neurotrophic agents, their symptoms remained inadequately controlled, with pain scores ranging from 8 to 10. After undergoing trigeminal ganglion electrical stimulation, the pain score of both patients dropped to 2-3 on the first day post-treatment, with significant improvement in the herpes zoster blisters and pain. During follow-up, the pain continued to improve, with marked reduction in the pain and itching in the affected areas, and sleep quality also improved. At 1, 3, and 6 months of follow-up, neither patient had developed postherpetic neuralgia. These cases suggest that trigeminal ganglion electrical stimulation may be an effective method for treating refractory trigeminal herpes zoster and preventing postherpetic neuralgia, significantly improving herpes symptoms and alleviating pain.
conclusionsThese cases demonstrate that trigeminal ganglion electrical stimulation can provide rapid and sustained pain relief while preventing postherpetic neuralgia in refractory trigeminal herpes zoster patients. This highlights the potential of trigeminal ganglion electrical stimulation as a novel therapeutic approach, particularly for patients who do not respond to conventional treatments. Its success in these cases suggests a promising direction for further research and clinical application.
