MultiColor imaging in urticarial vasculitis with recurrent branch retinal artery occlusion in a case with positive toxoplasma IgG and interferon-gamma release assay - Case report.
Article in American journal of ophthalmology case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionWe report a male who presented with acute visual defect and was diagnosed with urticarial vasculitis with recurrent branch retinal artery occlusion (BRAO) after systemic disease survey, fluorescein angiography (FA), and MultiColor imaging (MCI). CASE REPORT: A 47-year-old male with a history of urticarial vasculitis presented with visual defect OD. Fundus examination showed two foci of ischemic retinal whitening beneath the inferior arcade and above the superior arcade. MCI demonstrated a greenish tinge in the corresponding area. FA revealed segmental arteriolar staining and arterial occlusive changes. BRAO with retinal arteritis was diagnosed. Toxoplasma IgG was positive. Sulfamethoxazole 400mg plus trimethoprim 80mg was given. His vision worsened after 1-week of treatment. The established lesions improved, but new lesions occurred. Interferon-gamma release assay was positive but tuberculosis DNA qualitative amplification test of sputum was negative. Sputum acid-fast stain was positive and culture revealed nontuberculous mycobacteria. Left facial itching and reactive lymphadenopathy developed. Prednisolone and cyclophosphamide were started. The initial retinal artery lesions regained perfusion.
conclusionsUrticarial vasculitis with recurrent BRAO is an immune complex-mediated disease. Greenish-tinged occlusive lesions were noted from MCI with high resolution and contrast. MCI could be a valuable method for retinal vessel occlusive disease detection before FA and follow up.
