Psychosocial, Behavioral, and Quality of Life Insights in TMDs: A Comparative Exploration of Young and Mature Patients.
Article in Journal of pain research, 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: Despite its global adoption and translation, studies reporting age-stratified Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I and II findings remain scarce. This study aimed to 1) compare TMD diagnostic categories, psychosocial/behavioral profiles, and Oral Health-related Quality of Life (OHRQoL) across age groups, 2) explore correlations between psychosocial/behavioral variables and OHRQoL, and 3) identify factors associated with low OHRQoL among Chinese adult TMD patients. Methods: A total of 798 participants were recruited from a dental hospital and categorized into: young (YA: 18-44), mature patients (MA: 45-64), and old patients (OA: ≥65 years). They were assessed using DC/TMD Axis I procedures and Axis II measures for depression, anxiety, oral behaviors, and jaw function. OHRQoL was evaluated with the Oral Health Impact Profile for TMDs. Statistical analyses were performed using Chi-square/non-parametric tests and logistic regression (α = 0.05). Results: The final sample included 798 participants (79.6% women), of whom 88.0%, 11.0%, and 1.0% were YA, MA, and OA, respectively. Significant differences in education level (YA > MA/OA), intra-articular TMDs (YA > MA), jaw overuse behaviors (YA > MA/OA), jaw functional limitation (MA > YA), and OHRQoL (MA > YA) were observed. Moderate correlations were noted between OHRQoL and depression, anxiety, and jaw functional limitation ( Conclusion: Mature (MA/OA) TMD patients exhibited reduced oral behaviors but experienced greater jaw function and OHRQoL impairments. TMD pain doubled the likelihood of low OHRQoL. Clinical Relevance: Age-related differences in physical diagnosis, oral behaviors, jaw function, and OHRQoL are evident among TMD patients. Older individuals exhibit fewer oral behaviors but face greater jaw limitations and poorer OHRQoL, highlighting the importance of tailored management across age group.
