Retinal thickness and microvascular alterations in the diagnosis of behcet's disease: a case-control study.
Article in BMC medical imaging, 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
backgroundIn the current study optical coherence tomography angiography (OCTA) was used to compare retinal thickness (RT) and superficial vascular density (SVD) in patients with Behcet’s disease (BD) and healthy controls.
methodsThe study included 17 BD patients (34 eyes) and 17 healthy participants (34 eyes). Each eye had an en-face OCTA scan. Macular RT and SVD were assessed in both groups after segmenting each image into 9 subregions.
resultsBD patients and controls had significantly different visual acuity (p < 0.001). Compared to the control group, BD patients had increased inner RT in the inner superior, inferior, temporal, outer superior, inferior, and center regions, and increased full RT in the inner inferior, outer inferior and superior regions (p < 0.05). RT was positively correlated with visual acuity in the outer and full retina at outer temporal regions (p < 0.05). Also, c-reactive protein was positively correlated with full and outer RT in the center region in patients with BD (p < 0.05). The area under the receiver operating characteristic curve for the outer nasal region of the SVD was 0.913 (95% confidence interval: 0.835–0.991).
conclusionThe OS region of full RT and the II region of inner RT in the macular region may serve as a diagnostic marker for BD, and has clinical significance for auxiliary imaging diagnosis.
