Temporomandibular joint disorder in rheumatoid arthritis: A cross-sectional ultrasonographic study.

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
Objectives: This study aims to investigate temporomandibular joint (TMJ) involvement and dysfunction in patients with rheumatoid arthritis (RA) clinically and ultrasonographically (USG). Patients and methods: Between May 2021 and November 2021, a total of 51 patients with RA (16 males, 35 females; mean age: 53.0±10.4 years; range, 18 to 65 years) and 51 age- and sex-matched healthy controls (16 males, 35 females; mean age: 51.3±6.9 years; range, 18 to 65 years) were recruited. The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) form was applied to both groups. Pain intensity for both TMJs was measured with the Visual Analog Scale (VAS). The Health Assessment Questionnaire (HAQ) was used to measure the functional capacities. Disease activity of patients with RA was evaluated with the Disease Activity Score-28 (DAS28). All participants included in the study underwent TMJ USG examination. Results: According to the DC/TMD diagnostic decision tree, pain disorder was detected in 22 (43.1%) patients with RA and 12 (23.5%) in the healthy control group. Joint disorder was diagnosed in 14 (27.5%) of the RA patients and five (9.8%) of the healthy control group. Since the disc thickness was found to be significantly higher in patients with TMJ pain disorders in our USG evaluations, we performed receiver operating characteristic (ROC) analysis to determine the diagnostic cut-off value. As a result of ROC analysis, we determined the disc thickness cut-off value as 1.55 mm for the diagnosis of temporomandibular dysfunction (TMD). Conclusion: These findings support that USG, which is non-invasive, without X-ray exposure, applied from a single source and easily accessible, is a viable method in the diagnosis of TMD.
