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

purposeErythropoietin (EPO) is a promising neuroprotective agent and is currently in Phase III clinical trials for the treatment of traumatic brain injury. The goal of this study was to determine if EPO is also protective in traumatic eye injury.

methodsThe left eyes of anesthetized DBA/2J or Balb/c mice were exposed to a single 26 psi overpressure air-wave while the rest of the body was shielded. DBA/2J mice were given intraperitoneal injections of EPO or buffer and analyses were performed at 3 or 7 days post-blast. Balb/c mice were given intramuscular injections of rAAV.EpoR76E or rAAV.eGFP either pre- or post-blast and analyses were performed at 1 month post-blast.

resultsEPO had a bimodal effect on cell death, glial reactivity, and oxidative stress. All measures were increased at 3 days post-blast and decreased at 7-days post-blast. Increased retinal ferritin and NADPH oxygenases were detected in retinas from EPO-treated mice. The gene therapy approach protected against axon degeneration, cell death, and oxidative stress when given after blast, but not before.

conclusionsSystemic, exogenous EPO and EPO-R76E protects the retina after trauma even when initiation of treatment is delayed by up to 3 weeks. Systemic treatment with EPO or EPO-R76E beginning before or soon after trauma may exacerbate protective effects of EPO within the retina as a result of increased iron levels from erythropoiesis and, thus, increased oxidative stress within the retina. This is likely overcome with time as a result of an increase in levels of antioxidant enzymes. Either intraocular delivery of EPO or treatment with non-erythropoietic forms of EPO may be more efficacious.
