The effects of anti-vascular endothelial growth factor agents on human retinal pigment epithelial cells under high glucose conditions.
Article in International journal of ophthalmology, 2017. 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
aimTo investigate the effects of high glucose levels and anti-vascular endothelial growth factor (VEGF) agents (bevacizumab, ranibizumab and aflibercept) on retinal pigment epithelium (RPE) cells.
methodsARPE-19 cells were cultured at different glucose levels (5.5 mmol/L, 25 mmol/L, and 75 mmol/L). Cell viability was evaluated by MTT assay at 3d after treatment with D-glucose. Cell migration ability was measured by wound healing assay at 3d. A cell death detection kit was used to assess apoptosis at 3 and 14d. Cell proliferation was assessed by EdU assay at 3d. The culture medium was treated with anti-VEGF agents at clinically relevant concentrations. The experiment was then repeated at a different glucose level.
resultsThe viability and migration of ARPE-19 cells were significantly decreased in the presence of 75 mmol/L as compared to 5.5 mmol/L glucose. The percentage of TUNEL-positive cells was significantly increased and the proliferative potential was decreased with 75 mmol/L compared to 5.5 mmol/L glucose. There were no significant differences in the results between 25 mmol/L and 5.5 mmol/L glucose. In the presence of 75 mmol/L glucose, the groups treated with anti-VEGF showed decreased cell viability and proliferation and increased apoptosis. However, there were no significant differences between the anti-VEGF groups.
conclusionHigh glucose level decreases the viability, wound healing ability, and proliferation of RPE cells, while increasing apoptosis. Furthermore, anti-VEGF agents interfered with the physiological functions of RPE cells under high-glucose conditions, accompanied by decreases in cell viability and proliferation.
