Erythropoietin as a treatment option for indirect traumatic optic neuropathy: A pilot study.
Article in Indian journal of ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Purpose: Our study aims to evaluate the effectiveness of intravenous erythropoietin (EPO) in patients with indirect traumatic optic neuropathy (TON), assess the side effects, and compare the visual function results among three groups of patients who had received different treatment options - EPO, steroids, and observation. Methods: : Patients with indirect TON presenting to the neuro-ophthalmology clinic from August 2019 to March 2020, were assigned to three groups, with six patients in each group. In group 1, patients were recruited prospectively and received recombinant human erythropoietin, whereas, in groups 2 and 3, patients were recruited retrospectively and received intravenous methylprednisolone followed by oral steroids and multivitamins, respectively. Groups 1 and 2 included patients presenting within 2 weeks of trauma, whereas group 3 included those presenting beyond that. Best-corrected visual acuity, pupillary reaction, color vision, and visual fields following treatment were measured. Results: Initial visual acuity in the EPO group ranged from 20/80 to no perception of light (No PL). The mean initial BCVA (1.82 logMAR, standard deviation [SD] = 0.847) improved to 1.32, SD = 0.93 logMAR after treatment recorded at the third month (P = 0.0375), with no significant adverse effects. The initial BCVA of group 2 ranged from 20/120 to No PL. The mean initial BCVA (1.95, SD = 0.77 logMAR) improved to 1.45 logMAR, SD = 0.97 after treatment (P = 0.0435) but three patients had side effects of steroids. Initial visual acuity in Group 3 ranged from 20/40 to no PL. The mean initial BCVA (1.09 logMAR, SD = 1.10) worsened to 1.19 logMAR, SD = 1.06 after treatment after treatment (P = 0.0193). The improvement in BCVA when compared between the three groups was not significant. Conclusion: Both erythropoietin and steroids are effective in the management of traumatic optic neuropathy. However, erythropoietin shows lesser or no side effects when compared to steroids.
