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
Dye eye disease (DED) is a common ocular disorder in patients with diabetes. It has been reported that APX-115A, a pan-nicotinamide adenine dinucleotide phosphate (NAPDH) oxidase inhibitor, has an apoptosis-inducing effect on Epstein-Barr virus-infected retinal epithelial cells, but its effects in DED are poorly understood. Therefore, a rat model of diabetes was used in the present study to investigate whether APX-115A has an impact on DED in diabetic rats. A diabetic model was established in male Sprague Dawley rats via the intraperitoneal injection of streptozotocin. The eyeballs of the rats were treated with a solution containing APX-115A or a saline control. Tear secretion was measured with the phenol red thread tear test, and the morphology of the eyeball and lacrimal gland tissues was determined using hematoxylin and eosin staining. In addition, localization of NAPDH oxidase 2 (NOX2) in the eyeball and lacrimal gland tissues was detected by immunohistochemistry. The APX-115A treatment had no effect on body weight, blood glucose level or the size of the lacrimal glands. However, morphological changes, namely intracellular vacuoles and acinar atrophy, were observed in the lacrimal glands of the diabetic rats, and APX-115A treatment attenuated these changes. Immunohistochemistry revealed that NOX2 expression was decreased in the lacrimal glands of the diabetic rats, and APX-115A treatment did not attenuate the reduction in NOX2. The corneas of the diabetic rats treated with APX-115A exhibited no change in thickness but had lower NOX2 expression levels compared with those of the control diabetic rats. APX-115A also increased tear secretion and ameliorated the histological changes associated with diabetes. Furthermore, the NOX2 expression levels in the corneas of the diabetic rats treated with APX-115A were restored to the levels observed in normal rats. These findings suggest that APX-115A has potential as a therapeutic agent for DED.
