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
backgroundTrigeminal neuralgia (TN) is a rare and debilitating condition characterized by severe, episodic facial pain, with an incidence of about five individuals per 100 000 annually, predominantly affecting women aged 50-70 years. TN is often difficult to diagnose; leading to underestimation or misdiagnosis and prolonged patient suffering.
objectiveThis study aimed to assess masticatory dysfunction in individuals with and without TN using an electromyographic device ("Chewing") and evaluate its potential to quantify pain-related dysfunction and inform treatment approaches.
methodsThis observational study assessed masticatory dysfunction in TN patients and healthy controls using "Chewing" device. Masticatory behavior was monitored with apple and carrot as test foods, and parameters such as chewing time, number of chews, and chewing force were recorded. Participants were clustered based on masticatory patterns using an unsupervised learning approach.
resultsTwo distinct clusters of masticatory behavior emerged from the analysis. Cluster 1, representing 27.5% of TN1 patients, was characterized by prolonged chewing duration, a greater number of chewing cycles, and reduced chewing force compared to Cluster 0. Specifically, during apple mastication, Cluster 1 showed a 24% increase in chewing time (p = 0.02), a twofold increase in the number of chews (p < 0.001), and a 50% reduction in chewing force (p < 0.001). When chewing carrots, the number of chews increased by 57% (p < 0.001), while chewing force decreased by 64% (p < 0.001). Chewing frequency was also significantly higher in Cluster 1 for both food types (p < 0.001). Furthermore, a higher prevalence of TN1 patients was found in Cluster 1 compared to Cluster 0 (χ
conclusions"Chewing" device successfully quantified and differentiated masticatory patterns, providing valuable insights into functional adaptations. Subgrouping TN patients by masticatory behavior may guide personalized treatment strategies and improve patient outcomes.
