Vasculature alteration of foveal zone in systemic lupus erythematosus: a Meta-analysis.
Article in International 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
aimTo summarize and quantitatively evaluate vasculature alteration of foveal zone in systemic lupus erythematosus (SLE) patients by secondary literature analysis.
methodsA systematic search of PubMed, Embase, Web of Science, Cochrane Library, CBM, CNKI WanFang Data and VIP was conducted. Studies were about retinal vessel density in SLE patients from January 2000 to April 2023 and valid data were extracted. The Joanna Briggs Institute (JBI) critical appraisal checklist was used to evaluate the cross-sectional studies and prospective studies. The measurement data for combined effect size were weighted mean difference (WMD) and 95% confidence interval (CI). The heterogeneity was evaluated by
resultsA total of 14 studies with 445 subjects and 441 healthy controls from 9 countries were enrolled and 11 studies were included in Meta-analysis. The JBI scores of studies were no less than 14 points. The Meta-analysis results indicated that mean parafoveal superficial vessel density (SVD; WMD=-1.22, 95%CI: -1.67, -0.76), mean perifoveal SVD (WMD=-1.42, 95%CI: -1.95, -0.89), mean whole SVD (WMD=-1.66, 95%CI: -2.53, -0.79), mean parafoveal deep vessel density (WMD=-1.67, 95%CI: -2.75, -0.59) and mean whole deep vessel density (WMD=-4.09, 95%CI: -7.67, -0.52) was significantly lower than the control, while mean foveal SVD (WMD=-1.71, 95%CI: -4.65, 1.24), mean foveal avascular zone (FAZ) area (WMD=0.04, 95%CI: -0.01, 0.09) and mean acircularity index (AI; WMD=0.00, 95%CI: -0.02, 0.02) were not different between SLE patients and controls. Subgroup analysis indicated that the heterogeneity in SVD was partially due to the scanning area. Ocellus or binoculus data contributed partially to the heterogeneity in parafoveal deep vessel density and FAZ area. Sensitivity analysis indicated that the results were robust after changing the analysis model except for foveal SVD and FAZ area. There was no bias in included studies except whole SVD.
conclusionParafoveal superficial and deep vessel density are significantly lower in SLE patients while FAZ area and AI are not different between SLE patients and the control.
