Clinical and Psychological Profiles of Patients With Subclinical Versus Self-Reported Painful Temporomandibular Disorders.
Article in Journal of oral rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
objectiveTo compare clinical examination findings, functional limitations, and psychological profiles between patients with subclinical temporomandibular disorders (TMD) and those with self-reported painful TMD. MATERIALS AND
methodsThis cross-sectional study investigated 98 subclinical TMD patients and 262 self-reported painful TMD patients attending a specialised orofacial pain clinic. Subclinical TMD was defined as positive palpation findings without muscle or joint pain complaints. Self-reported painful TMD required both pain complaints and positive clinical findings. Validated questionnaires assessed jaw functional limitations (JFLS-20), depression (PHQ-9), stress (SPST-20), and oral behaviours (OBC). Statistical analysis used Mann-Whitney U tests and chi-square tests with Bonferroni correction.
resultsSelf-reported painful TMD patients were significantly older (median age 39 vs. 31 years, p = 0.003), showed greater jaw functional limitations (JFLS global score: 1.88 vs. 0.75, p < 0.001), and higher depression scores (PHQ-9: 1.0 vs. 0.0, p < 0.001). Sleep bruxism frequency differed significantly between groups (p < 0.001), with subclinical patients more commonly reporting frequent sleep bruxism. No significant differences were found in stress levels, overall oral behaviours, or daytime clenching frequency.
conclusionsPatients with self-reported painful TMD demonstrate distinct clinical profiles characterised by greater functional impairment and psychological distress compared to subclinical cases. CLINICAL RELEVANCE: These findings suggest different phenotypes within the TMD spectrum that may require tailored clinical approaches. Longitudinal studies are needed to determine whether subclinical TMD represents an early stage or a distinct entity.
