Prevalence of trigeminal neuralgia in Jincheng, China.
Article in Frontiers in neurology, 2025. 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
Objective: Trigeminal neuralgia (TN) is a debilitating neuropathic pain disorder that affects the trigeminal nerve, often causing intense facial pain. The prevalence and epidemiology of TN remain under-researched, particularly in China. This study aimed to estimate the lifetime prevalence of TN in Jincheng City, central China, and to provide an initial epidemiological insight into its occurrence within the Chinese population. Methods: A cross-sectional, descriptive epidemiological study was conducted from September to December 2024. A total of 1,350 individuals were surveyed using a 16-question screening questionnaire to assess symptoms of TN. TN diagnoses were based on the third edition of the International Classification of Headache Disorders (ICHD-3). Results: The final sample included 1,283 participants, with four diagnosed cases of TN, yielding a crude prevalence rate of 312 per 100,000 individuals (95% CI: 8-616 per 100,000). The mean age of the patients was 56.00 ± 9.59 years, and the female-to-male ratio was 3:1. The majority of patients (75%) had right-sided TN, with the maxillary and mandibular branches being most commonly affected. One case was classified as symptomatic TN due to multiple sclerosis, while the others were diagnosed with classical TN. All patients received pharmacological treatment, including carbamazepine and pregabalin. Conclusion: This study provides the first epidemiological data on TN prevalence in Jincheng City, China. The estimated prevalence aligns with findings from several international studies, though regional differences remain. The female predominance in TN cases and the higher incidence of right-sided involvement are consistent with global trends. Further studies with larger sample sizes and updated diagnostic criteria are needed to explore potential regional and genetic factors influencing TN prevalence and to assess the long-term impact of TN on public health in China.
