Retrospective pilot study on the correlation between masseter muscle volume and myocardial function parameters.
Article in Oral radiology, 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
objectivesThis study aimed to investigate whether there is an association between masseter muscle volume and myocardial function parameters.
methodsData from 38 patients who underwent both multi-slice coronary CT angiography and contrast-enhanced neck CT angiography were analyzed. Myocardial function parameters were calculated using coronary CT angiography. Masseter muscle volumes were measured separately on the right and left sides from neck CT images, and the mean value for each patient was included in the analysis. Correlations were evaluated with Pearson’s test for normally distributed data and Spearman’s test for non-normally distributed data. Regression analyses were performed to assess whether significant correlations were independent of age and sex.
resultsMasseter muscle volume showed significant positive correlations with RV End-Diastolic Volume (r = 0.321, p = 0.049) and LV Myocardial Mass (r = 0.548, p < 0.001) in Pearson analysis. Spearman analysis revealed significant associations with RV End-Systolic Volume (ρ = 0.421, p = 0.008), LV Myocardial Volume (ρ = 0.588, p < 0.001). After adjustment for age and sex, associations with LV Myocardial Mass (β = 2.530, p = 0.012) and LV Myocardial Volume (β = 2.189, p = 0.014) remained significant, whereas correlations with RV End-Diastolic and End-Systolic Volumes were no longer significant.
conclusionThe strong correlations observed between masseter muscle volume and both LV myocardial mass and volume suggest that masseter muscle volume may serve as a potential predictor of myocardial function parameters. These findings indicate a possible link between cardiac and masticatory muscles, warranting further detailed investigation.
