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

purposeTo assess the interaction between ranibizumab, aflibercept, and mouse vascular endothelial growth factor (VEGF), both in vivo and in vitro.

methodsIn vivo, the effect of intravitreal injection of ranibizumab and aflibercept on oxygen induced retinopathy (OIR) and the effect of multiple intraperitoneal injections of ranibizumab and aflibercept on neonatal mice were assessed. In vitro, the interaction of mouse VEGF-A with aflibercept or ranibizumab as the primary antibody was analyzed by Western blot.

resultsIn both experiments using intravitreal injections in OIR mice and multiple intraperitoneal injections in neonatal mice, anti-VEGF effects were observed with aflibercept, but not with ranibizumab. Western blot analysis showed immunoreactive bands for mouse VEGF-A in the aflibercept-probed blot, but not in the ranibizumab-probed blot.

conclusionsAflibercept but not ranibizumab interacts with mouse VEGF, both in vivo and in vitro. When conducting experiments using anti-VEGF drugs in mice, aflibercept is suitable, but ranibizumab is not.
