Morphometric analysis of extraocular muscles and proptosis by computed tomography in Graves' orbitopathy.
Article in Radiologia brasileira. 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
Objective: To assess the prevalence of changes on computed tomography (CT) in Graves' orbitopathy (GO) and to correlate those changes with disease activity, as well as with clinical and biochemical variables. Materials and Methods: This was a retrospective study, conducted at a tertiary hospital, of clinical, biochemical, and imaging data from consecutive patients with GO who underwent at least one orbital CT scan between July 2012 and December 2020. A single observer quantified the thickness of the extraocular muscles and the degree of proptosis. Clinical and biochemical variables were analyzed to determine whether they correlated with CT changes, GO activity, and GO severity. Results: Our sample included data from 67 patients with GO (134 orbits), 50 (74.6%) of whom were female. There were positive correlations between the clinical activity score and increase in thyroid-stimulating factor/free thyroxine, between the severity of GO and the increase in the thickness of the extraocular muscles, and between the degree of proptosis and muscle thickness. Conclusion: Orbital CT proved effective in detecting thickening of the extraocular muscles and proptosis in patients with GO, changes that correlated significantly with clinical and biochemical variables. Muscle thickening was associated with the severity of GO and could be a biomarker of the risk of vision loss.
