An Unusual Case of Giant Cell Arteritis (GCA) Presenting With Bilateral Visual Loss.
Article in Cureus, 2026. 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
We report the case of a 77-year-old woman who presented with progressive, painless bilateral visual loss over three weeks. Ophthalmologic evaluation demonstrated bilateral anterior ischemic optic neuropathy and right central retinal artery occlusion. Notably, she lacked classical systemic features of giant cell arteritis (GCA), including headache, scalp tenderness, or jaw claudication. Laboratory evaluation revealed an elevated erythrocyte sedimentation rate (ESR 64 mm/h). Temporal artery ultrasound demonstrated bilateral halo signs, supporting the diagnosis of GCA. High-dose corticosteroid therapy was promptly initiated; however, visual loss remained irreversible. This case highlights the importance of maintaining a high index of suspicion for GCA in elderly patients presenting with unexplained visual symptoms, even in the absence of typical cranial features. Temporal artery ultrasound is a valuable non-invasive diagnostic tool that can facilitate early diagnosis and prompt treatment, potentially preventing irreversible visual complications.
