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

backgroundThe glycoprotein erythropoietin (EPO) has been shown to be protective in models of neuronal disease and reduced apoptosis of retinal ganglion cells (RGC) after transection of the optic nerve and in glaucoma. In this study we assessed in vivo the properties of EPO on survival of RGC after ischemia and optic nerve compression, as well as on postischemic visual function. Furthermore, the safety of intravitreal injection was assessed.

methodsIn all experiments, EPO was administered intravitreally in male Brown Norway rats. Ocular ischemia was induced by elevating the intraocular pressure for 55 min. The calibrated optic nerve compression was performed for 10 s. RGC were marked stereotactically and quantified by fluorescence microscopy. The retinal function was quantified by electroretinography (ERG) and the whole visual pathway by visual evoked potential (VEP).

resultsEPO (2 and 20 units per eye, n=9-21) increased the survival of RGC after ischemia by 21+/-21% and 127+/-31% (mean +/- SEM) and after optic nerve compression by 28+/-12% and 58+/-13%. With EPO (20 units), postischemic function was increased, in ERG by 71+/-13% (a-wave) and 75+/-19% (b-wave) and in VEP by 264+/-65% (p=0.053). Neither the ERG parameters, nor the VEP, nor the number of RGC differed significantly after intravitreal injection of EPO (5, 50, and 200 units, n=6-7) in healthy eyes.

conclusionThe combination of toxicological safety and protection of retinal neurons makes EPO a promising drug for ischemic retinal diseases and traumatic optic neuropathy.
