Heterogeneity in mouth opening function among patients with oral cancer following surgery: A latent profile analysis.

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: This study aimed to identify heterogeneous subtypes of mouth opening function in patients after oral cancer surgery and explore factors associated with mouth opening function profiles. Methods: We recruited 305 patients who underwent oral cancer surgery at the Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University, Changsha, China, between April and September 2025. Data were collected using a general information questionnaire, measurements of maximum interincisal opening, the Gothenburg Trismus Questionnaire, and the Tampa Scale of Kinesiophobia for Temporomandibular Disorders. Latent profile analysis (LPA) was used to identify subtypes of mouth opening function, followed by multinomial logistic regression to determine the associated factors. Results: Three subtypes were identified through LPA among included postoperative patients with oral cancer: well-functioning with mild symptoms (28.2%, Conclusions: Using a subjective-objective combined assessment method, this study identified three distinct mouth opening function subgroups in postoperative oral cancer patients. Each subgroup exhibited distinct characteristics and was associated with a combination of factors. These findings may provide a useful basis for early identification and for developing future targeted intervention strategies according to the characteristics of each subtype.
