Correlation between disc-condyle relationship and the efficacy of conservative treatment in patients with anterior disc displacement without reduction.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 investigate the correlation between the positional relationship of the TMJ disc and condyle on MRI and the therapeutic efficacy of temporomandibular intra-articular injection in patients with Anterior Disc Displacement without Reduction(ADDWoR). MATERIALS AND
methodsRetrospectively included 74 patients (74 joints) with ADDWoR who completed four temporomandibular intra-articular injections and underwent 3-month follow-up. On MRI images at closed-mouth and maximum-opening positions, measured the disc angle relative to the condyle before treatment(Angle), and the disc anterior displacement distance (Distance). Spearman’s rank correlation analysis assessed monotonic relationships between variables. Locally Estimated Scatterplot Smoothing(LOESS) fitted nonlinear trends, with statistical significance tested via the smoothing term in Generalized Additive Models (GAM). The R² value of the LOESS fit was calculated to quantify model explanatory power. Additionally, to determine the optimal cutoff value of the Angle metric for predicting treatment efficacy, ROC curve analysis was performed, and the optimal discriminative threshold was identified by maximizing the Youden index.
resultsScatter plots reveal an S-shaped correlation between Angle and maximum mouth opening (MMO) before and after treatment, while Angle shows a W-shaped correlation with ∆MMO and ∆VAS. ROC curve analysis and determination of the optimal cutoff point by maximizing the Youden index indicate that the optimal cutoff is -20.65°.
conclusionsThis study establishes an MRI based cutoff of -20.65° for the Angle as a preliminary indicator that may help clinicians rapidly identify ADDWoR patients(Patients with Angle < − 20.65°) unlikely to benefit from Sodium Hyaluronate injections(HA). CLINIC RELEVANCE: An MRI derived disc angle relative to the condyle of ≤ − 20.65° can serve as a preliminary indicaor of ADDWoR patients who are unlikely to benefit from temporomandibular intra-articular HA injections, thereby facilitating timely referral for other intervention and safeguarding the optimum window for osteoarthritic change management.
