Aganirsen as a Therapeutic Alternative for Modulating Corneal Neovascularization: A Real-World Case Series Study.

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: To assess the clinical benefits of aganirsen, an antisense oligonucleotide targeting insulin receptor substrate-1 (IRS-1), for reducing corneal neovascularization (CoNV) in patients scheduled for corneal transplantation. Patients and Methods: Retrospective cohort study of patients who were treated with 1 drop of aganirsen (0.86 mg/mL) twice daily during 1 week preoperatively and at least 3 months after surgery. Changes in neovascularization were assessed qualitatively on slit-lamp examination. Results: The study population included 65 patients (males 61.5%), with a mean age of 60.3 years. Bilateral CoNV was observed in 1 patient only (1.5%). Main diagnoses included corneal dystrophy in 61.5% of patients, transplant rejection in 10.8%, herpes simplex keratitis and leucoma in 7.7% each, and mechanical trauma in 3.1%. A reduction of neovascularization was observed in all eyes (100%) after 3 months of treatment. Results were not influenced by demographic characteristics or diagnosis. Treatment with aganirsen made graft surgery unnecessary in 3 out of 65 patients (4.6%). Failure of corneal transplantation occurred in 5 out of 62 patients (8.1%). Diagnosis at presentation in these 5 patients were corneal dystrophy in 2, previous transplant rejection in 2, and herpetic keratouveitis in 1. Some patients presented minor conjunctival hyperemia, and 1 patient reported pruritus and discontinued the study at 2 months of treatment. Conclusion: This real-world study of the use of aganirsen months starting 1 week before graft surgery adds evidence of the clinical benefits of this agent in modulating neovascularization. Standardizing and extending the duration of treatment with aganirsen may further optimize the outcome of corneal transplantation.
