Ultrasound in GCA: Halo Sign Quantification and Visual Symptoms, Systemic Inflammation and Relapse Risk.
Article in Mediterranean journal of rheumatology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: A sonographic scoring system, termed Halo count and Halo score, of temporal and axillary arteries (TAXA) in suspected giant cell arteritis (GCA) has been proposed for outcome prognostication. Method: We conducted a retrospective review into the relationship of Halo count and Halo score and clinical-laboratory parameters amongst patients diagnosed with GCA via our rapid-access pathway to determine whether these measures should form part of our local routine clinical practice. Result: This review of TAXA ultrasound (US) images in patients with diagnosed GCA did not identify any correlation between Halo count/score and ocular symptoms, jaw claudication, 6-month relapse risk or inflammatory markers. Conclusion: This suggests that further prospective evaluation of Halo count and -score is required before adopting these measures into routine US scanning of TAXA for suspected GCA.
