Contrast-enhanced MRI compared to direct joint visualization at arthroscopy in pediatric patients with suspected temporomandibular joint synovitis.
Article in Pediatric radiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundContrast-enhanced magnetic resonance imaging (MRI) has become the gold standard when assessing the temporomandibular joint (TMJ) in children. To our knowledge, no previous pediatric study has compared findings of TMJ MRI with direct visualization of the joint using arthroscopy.
objectiveTo determine if subjective findings on contrast-enhanced MRI of the temporomandibular joint correlate with arthroscopic findings of acute and chronic inflammation of the TMJ in children. MATERIALS AND
methodsPatients who had temporally related TMJ arthroscopy and contrast-enhanced TMJ MRI between March 2014 and March 2016 were identified. Imaging was retrospectively reviewed by two radiologists for erosions, condyle shape, bone marrow edema, effusion, severity of synovitis, joint space width measured in the coronal plane and enhancement ratio of the synovium relative to ipsilateral temporal lobe white matter. Joint space width was included because synovial thickening could widen the joint space. TMJ arthroscopy findings assessed included indicators of acute inflammation (active synovitis, number of joint sites affected, presence of retrodiscitis) and markers of chronic inflammation (hyperplastic synovitis, adhesions, disc perforation, chondromalacia). A Total Synovitis Score was given to all patients on arthroscopy, which multiplied the severity of active synovitis (0-4) with the number of joint recesses affected. Data were compared using the Fisher exact test and a P-value <0.05 was considered significant.
resultsThere was no significant correlation between subjective synovitis on MRI and active synovitis on arthroscopy; however, there was a significant correlation between joint space width and hyperplastic synovitis (P=0.04, 3.7 mm±0.8 vs. 2.9 mm±0.6) and a trend toward significance between subjective synovitis (P=0.08) and enhancement ratio of synovium (P=0.06) on MRI and hyperplastic synovitis on arthroscopy.
conclusionJoint space width and subjective synovitis on TMJ MRI correlate with arthroscopic findings of chronic synovitis. Increased joint space width may be useful when evaluating the TMJ with less time-intensive modalities, such as ultrasound. However, MRI findings did not correlate well with findings of acute inflammation on arthroscopy.
