1 · What the graph read from it

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.

2 · The registry

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

purposeThis study aims to investigate the levels of aqueous vascular endothelial growth factor (VEGF) in diabetic patient groups in comparison to normal subjects, and to correlate elevated VEGF with the severity of diabetic retinopathy (DR). MATERIALS AND

methodsAqueous samples were obtained from 78 eyes of 74 patients undergoing intraocular surgery and they were examined by the enzyme-linked immunosorbent assay. Color photographs, optical coherence tomography scans, and fluorescein angiography were used to evaluate patients preoperatively.

resultsA strong statistical correlation was found to exist between the level of aqueous VEGF and the severity of DR ( P < 0.001), whereas, the VEGF levels in a control group and a diabetic group without DR were not significantly different ( P = 0.985). Aqueous VEGF levels were significantly elevated in patients with proliferative DR (PDR) as compared to the control group ( P < 0.001), to diabetic patients without retinopathy (NDR) ( P < 0.001), and to diabetic patients with nonproliferative DR (NPDR) ( P < 0.001). The aqueous VEGF levels were significantly higher in patients with active PDR than in those with quiescent PDR ( P = 0.001). On the other hand, a statistically insignificant ( P = 0.065) correlation was found between elevated aqueous VEGF and the presence of macular edema in the NPDR group.

conclusionsVEGF was elevated in the aqueous humor of patients with DR compared to that in normal eyes. The aqueous VEGF level had a strong correlation with the severity of retinopathy along with a statistically insignificant difference in macular edema.
