Craniofacial Pain and Disability Inventory and Tampa Scale for Kinesiophobia for Temporomandibular Disorders: A Study of Responsiveness and Minimal Important Change.
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. 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
backgroundCraniofacial Pain and Disability Inventory (CF-PDI/Brazil [Br]) assesses Temporomandibular Disorders (TMD)-related disability, and the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK/TMD-Br) assesses kinesiophobia in patients with TMD.
objectiveTo evaluate the responsiveness and interpretability of CF-PDI/Br and TSK/TMD-Br scores in chronic TMD patients.
methodsA total of 148 participants of both sexes (38, SD = 10.9 years) were included. Participants were reassessed after undergoing a 6-week rehabilitation treatment. Spearman correlations between change scores of the CF-PDI/Br and TSK/TMD-Br were compared with pain intensity and pain self-efficacy (responsiveness-construct approach). Accuracy (Area Under the Curve = AUC) was assessed by considering patients who improved or not, using the perceived global effect of improvement scale as an external anchor (responsiveness-construct approach). Interpretability assessed by minimal important change (MIC) estimate was also calculated using three methods: MIC
resultsCF-PDI and TSK/TMD exhibited suitable responsiveness. More than 75% of the hypothesized correlations between change scores for CF-PDI and TSK/TMD were confirmed, and both measures showed AUC > 0.70 to distinguish patients who improved from patients who did not improve. We found MIC
conclusionsCF-PDI/Br and TSK/TMD-Br demonstrated appropriate responsiveness and interpretability for patients with chronic TMD. The MIC values presented can be used to evaluate whether improvements in TMD-related disability and kinesiophobia are clinically meaningful. A change score decrease of at least -5.3 and -4 points in the total CF-PDI/Br and TSK/TMD-Br scores, respectively, indicates clinically significant improvement.
