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
Purpose: The dynamic changes of retinal microcirculation in Chinese Vogt-Koyanagi-Harada (VKH) patients have not yet been described. This study aimed to explore changes in retinal microcirculation among Chinese with VKH disease using optical coherence tomography angiography (OCTA) technology to determine whether patient outcomes improve due to therapeutic interventions. Methods: The study included 43 VKH patients and 43 normal controls. Vessel density (VD), perfusion density (PD), and the foveal avascular zone (FAZ) area, perimeter, and circularity were measured by OCTA. Clinical and demographic characteristics of VKH patients and visual acuity changes were recorded. All patients were treated with prednisone in combination with cyclosporine. Results: Before treatment, VD of the parafoveal and full area, PD of the parafoveal area, and visual acuity were significantly decreased in VKH patients compared to controls. These parameters increased significantly to normal values after 2 months of treatment and maintained a normal level thereafter. VD of the foveal area, PD of the foveal and full area, and FAZ area, perimeter, and circularity did not differ from those of normal eyes and showed no significant changes following treatment. A negative correlation was found between visual acuity and PD of the parafoveal and full area and FAZ area and circularity. Conclusions: Decreased retinal VD and PD were observed in Chinese VKH patients, which returned to normal values following treatment. OCTA analysis may be a useful method to follow the response of VKH patients to treatment. Translational Relevance: OCTA can objectively evaluate the retinal microcirculation and is an effective technology to track the response of VKH patients to treatment.
