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
objectivesTemporomandibular joint disorders (TMDs) require precise imaging of both osseous and soft-tissue components for accurate diagnosis. Current diagnostic protocols often necessitate separate cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) scans, increasing cost, complexity, and patient burden. This study aimed to develop and validate the Sivan 3D CBCT Volumetric Imaging Protocol, a novel post-processing technique designed to enable simultaneous high-resolution visualization of the temporomandibular joint (TMJ) disc, retrodiscal tissue, and adjacent osseous structures using a single CBCT data set.
methodsThis retrospective study analyzed anonymized CBCT volumes from 42 patients diagnosed with TMD. The data sets were processed using NNT software, incorporating dual-mode volumetric rendering, voxel intensity modulation, and anisotropic filtering. Fifteen expert raters assessed conventional CBCT, enhanced CBCT, and MR images across eight diagnostic parameters using a 5-point Likert scale. Inter- and intra-rater reliability was assessed using intraclass correlation coefficients (ICC), and statistical comparisons were performed using one-way ANOVA, Tukey's post-hoc test, and Cohen's d effect size analysis.
resultsEnhanced CBCT images showed excellent inter- and intra-rater reliability (ICC > 0.95) and significantly outperformed conventional CBCT and MRI in visualizing both soft and hard TMJ structures (p < 0.001), with large effect sizes (Cohen's d > 2.3), especially for disc and retrodiscal tissue delineation.
conclusionsThe Sivan 3D CBCT Volumetric Imaging Protocol provides a robust, single-modality alternative to MRI for comprehensive TMJ evaluation, improving diagnostic accuracy, efficiency, and accessibility in clinical settings with limited MRI availability.
