The effect of spleen tyrosine kinase inhibitor R406 on diabetic retinopathy in experimental diabetic rats.
Article in International ophthalmology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeTo investigate the effect of spleen tyrosine kinase (Syk) inhibitor R406 on diabetic retinopathy (DR) in diabetic mellitus (DM) rats.
methodsRats were randomized into Normal, DM, DM + 5 mg/kg R406 and DM + 10 mg/kg R406 groups. DM rats were established via injection of streptozotocin (STZ). One week after model establishment, rats in treatment groups received 5 mg/kg or 10 mg/kg R406 by gavage administration for 12 weeks consecutively, followed by the detection with hematoxylin-eosin (HE) staining, Evans blue angiography, retinal trypsin digestion assay, Western blotting, immunohistochemistry, TUNEL assay, immunofluorescence assay and quantitative reverse transcriptase real-time polymerase chain reaction (qRT-PCR).
resultsThe retina of DM rats presented different degree of edema, disordered and loose structure, swollen cells with enlarged intercellular space, and dilated and congested capillaries. Besides, the retinal vessels of DM rats showed high fluorescence leakage. However, R406 alleviated the above-mentioned conditions, which was much better with high concentration of R406 (10 mg/kg). R406 also reversed the down-regulations of occludin, claudin-5, ZO-1 and the up-regulation of and VEGF in retinal tissues of DM rats; inhibited retinal cell apoptosis; strengthened retinal cell proliferation; and reduced expressions of IL-1β, IL-6, TNF-α and nuclear p65 NF-κB in retinal tissues. The improvement in all these indexes was much more significant in rats of DM + 10 mg/kg R406 group than in rats of DM + 5 mg/kg R406 group.
conclusionSyk inhibitor R406 could attenuate retinal inflammation in DR rats via the repression of NF-κB activation.
