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

The retinal degeneration slow (rds/rds) mouse was used to test photoreceptor protection by systemic gene delivery of non-erythropoietic forms of erythropoietin (EPO). Two Epo mutants were generated and packaged into recombinant adeno-associated virus (rAAV) serotype 2/5, controls included rAAV2/5.Epo and rAAV2/5.enhanced green fluorescent protein (eGFP). Mice were injected in the quadriceps at postnatal day seven and analyses were performed at postnatal day 90. Hematocrit, serum EPO levels, and outer nuclear layer (ONL) thickness were quantified. Hematocrit and serum EPO levels in rAAV2/5.eGFP, rAAV2/5.Epo, and rAAV2/5.EpoR103E treated mice were: 46%, 8 mU/ml; 63%, 117 mU/ml; and 52%, 332 mU/ml, respectively. The ONL from rds/rds mice treated with the Epo vectors were approximately twice as thick as the negative controls. This demonstrates that the photoreceptors can be protected without performing an intraocular injection and without increasing the hematocrit to unsafe levels. Intramuscular delivery of rAAV.EpoR103E is an attractive treatment for retinal degenerative diseases.
