Intravitreal erythropoietin injection in late-stage optic neuropathy: a safety study on human.
Article in International ophthalmology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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 evaluate the whether intravitreal erythropoietin (EPO) administration has any beneficial or adverse effect in patients with late-stage optic neuropathy (ON) or not.
methodsThe study examined 16 eyes of 16 patients who had late-stage ON and ≥1/20 best-corrected visual acuity (BCVA) in their affected eye. There were nonarteritic ischemic ON in 10 (62.5%) eyes, traumatic ON in 4 (25.0%) eyes and methanol-induced ON in 2 (12.5%) eyes. Using pars plana approach, 2000 IU/0.2 ml EPO was administered intravitreally with a 30-gauge needle. Injections were administered three times with 6-week intervals. We compared the differences in the BCVA, intraocular pressure (IOP), retinal nerve fiber layer (RNFL) thickness, pattern visual evoked potentials (p-VEP) and pattern electroretinography (p-ERG) parameters performed at initial examination and final visits.
resultsThe mean age of the patients was 52.38 ± 12.00 years; 2 (12.50%) of them were female, and 14 (87.50%) of them were male. The mean BCVA levels of 16 patients with optic atrophy were 1.12 ± 0.25 logMAR at the initial examination and 1.08 ± 0.26 logMAR at the final visit (p = 0.102). There was no statistically significant difference between the initial and final RNFL thicknesses, IOP values, p-ERG or p-VEP responses.
conclusionsIntravitreal EPO injections have no beneficial or detrimental effect on the late stage of ON. Further studies are necessary to compare our results in patients with ON in earlier stages.
