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
purposeThis exploratory study aimed to determine whether non-experts in the field of temporomandibular disorders (TMDs) are capable of correctly assessing various intra-articular TMDs based on magnetic resonance imaging (MRI), and whether supplementing corresponding arthroscopic imaging findings will enhance accuracy of their assessments.
methodsNon-experts for the purposes of this study were recruited from German dental students. After a focused instruction on TMDs, they completed two evaluation rounds to identify and assess selected pathologies of arthrogenic TMDs in patient cases. Initially, participants were provided with MRI images only; in a second round, additional arthroscopic video material was provided. Statistical analysis was performed to evaluate responses, and inter-rater reliability among non-experts was determined.
results94 participants evaluated a total of 30 MRI scans of the temporomandibular joint (TMJ) obtained from 27 patients who had also undergone arthroscopy. Their assessment showed the relatively highest agreement with the correct diagnosis for disc perforations (68.2-71.9%) and when using both MRI and arthroscopy material. Synovitis showed the lowest agreement, and was more successfully detected based on arthroscopy (47.2%) alone. Overall, there was only slight to fair agreement among the study participants across diagnoses (Kappa 0.074-0.358). Non-experts showed significant inconsistencies in interpreting MRI and arthroscopic imaging, with only limited concordance with the actual diagnosis and an agreement rate of less than 71.9%.
conclusionDental students/Non-experts are unlikely to effectively interpret MRIs for the management of intra-articular TMDs based solely on their academic training. Enhanced curricular and postgraduate education in this area is therefore strongly recommended.
