Safety of anti-VEGF treatments in a diabetic rat model and retinal cell culture.
Article in Clinical ophthalmology (Auckland, N.Z.), 2019. 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 analyze the safety of different concentrations of anti-VEGF on retinal cells.
methodsNon-diabetic and streptozotocin (STZ)-induced diabetic rats received intravitreal rat anti-VEGF injections that had final vitreous concentrations of 0, 0.0625, 0.125 (clinical dose), and 0.25 mg/mL. Rats were also injected with the clinical dose of ranibizumab. TUNEL assay was performed on sectioned eyes to evaluate apoptotic cells. In vitro, rat retinal cell cultures were exposed to 0, 0.0625, 0.125 (clinical dose), and 0.25 mg/mL of ranibizumab for 48 and 72 hrs. Cellular metabolic activity was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, necrosis by lactate dehydrogenase (LDH), and apoptosis by cell death enzyme-linked immunosorbent assay (ELISA).
resultsDiabetic rats had a significant increase (
conclusionsAnti-VEGF treatment may be potentially detrimental to the retina by decreasing cellular metabolic activity and increasing cytotoxicity of retinal cells. The results provide a cautionary note to monitor both the retina and optic nerve status in patients undergoing frequent injections.
