Pain severity trajectory and influencing factors in children with recurrent aphthous stomatitis: a latent variable growth mixture model.
Article in Frontiers in pain research (Lausanne, Switzerland), 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
Objective: To explore the potential categories of pain intensity development trajectory in children with recurrent aphthous stomatitis and analyze the influencing factors of category differences. Methods: Conveniently select 200 children with recurrent aphthous stomatitis treated in our hospital from September 2023 to June 2025 as the research subjects, and retrospectively collect the pain dimension scores of the local body sign scores of oral ulcers at the time of visit (T0), as well as on the third day (T1), seventh day (T2), and fourteenth day (T3) after visit. The optimal number of categories was analyzed and named using a latent variable growth mixture model. Clinical data of the children were collected using a self-designed clinical data questionnaire. Independent influencing factors of potential category differences were analyzed by univariate analysis and multivariate logistic regression. Results: The pain intensity development trajectory of the 200 children with recurrent aphthous stomatitis could be divided into three potential categories: high pain level relief type (68 cases, 34.00%), moderate pain level improvement type (82 cases, 41.00%), and low pain level stable type (50 cases, 25.00%). Univariate and multivariate logistic regression analyses showed that for the high pain relief type, ulcer size, number of ulcers, ulcer type, frequency of attacks, and picky eating are independent influencing factors ( Conclusion: The development trajectory of pain severity in children with recurrent aphthous stomatitis exhibits certain heterogeneity and is influenced by factors such as ulcer size, number of ulcers, ulcer type, frequency of attacks, and picky eating habits. However, there are differences in the influencing factors of different trajectory categories. The above findings can provide reference for identifying high-risk pain trajectory children.
