Vascular characteristics of pediatric patients with familial Mediterranean fever: a study of optical coherence tomography angiography findings.
Observational study in Japanese journal of ophthalmology, 2025. 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
purposeThe aim of this study was to investigate the vascular characteristics of pediatric patients with familial Mediterranean fever (FMF) with homozygous c.~(p.M694V) mutations in the MEFV gene by comparing their retinal vascular densities with those of healthy controls by use of optical coherence tomography angiography (OCTA). STUDY
designProspective observational study.
methodsA total of 80 participants, 35 FMF pediatric patients and 45 healthy controls, were included in the study. The baseline demographic and clinical characteristics were examined, and OCTA was used to assess vascular densities in various regions of the superficial and deep capillary plexus (DCP) and optic disc. Statistical analyses were performed to identify significant differences between the groups.
resultsThe study demonstrated that patients with FMF exhibited a significant reduction in vascular density within the parafoveal deep capillary plexus (DCP) (P = 0.047). Additionally, vascular density in the inferior and temporal subregions of the perifoveal DCP was significantly lower in the FMF group than in the controls (P = 0.038 and P = 0.027, respectively), with a similar trend observed for the overall perifoveal DCP vascular density (P = 0.025). In addition, optic disc vascular density was significantly lower in the FMF patients than in the healthy controls (P = 0.026). Approximately 60% of the FMF patients had severe disease symptoms, whilst 40% of them had mild symptons.
conclusionsThe findings suggest significant reductions in deep capillary plexus and optic disc vascular density in children with FMF, further suggesting an underlying vascular pathology related to this autoinflammatory disease. Regular ophthalmic evaluations are necessary to monitor potential effects on retinal health in pediatric FMF patients, even when anterior segment examination findings are normal.
