Therapeutic efficacy of cenegermin in the management of neurotrophic keratitis: a systematic review and meta-analysis of randomized controlled trials.

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
Background: Neurotrophic keratitis (NK) is a rare, degenerative disease of the cornea that arises from impaired trigeminal nerve innervation. The condition leads to progressive corneal anesthesia, epithelial breakdown, ulceration, and potential perforation. Cenegermin, a recombinant form of human nerve growth factor, is the first pharmacotherapy approved for this indication and operates through a disease-modifying mechanism that promotes corneal nerve regeneration. Objectives: To evaluate the therapeutic efficacy and safety profile of topical cenegermin (20 mcg/mL) compared with vehicle in adults with moderate to severe NK (Mackie classification stage 2 or 3) by quantitatively synthesizing evidence from randomized controlled trials (RCTs). Design: Systematic review and meta-analysis of RCTs, conducted in accordance with the PRISMA 2020 statement and the Cochrane Handbook for Systematic Reviews of Interventions. Data sources and methods: PubMed, Web of Science, and Cochrane CENTRAL were searched from inception through February 2026. Two double-masked, vehicle-controlled RCTs (the REPARO trial and the NGF0214 trial) enrolling 148 adults were included. Data were pooled using random-effects models (DerSimonian-Laird) and reported as risk ratios (RRs) with 95% confidence intervals (CI). Risk differences (RDs) and the number needed to treat (NNT) were also computed. Certainty of evidence was appraised using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. Results: Cenegermin substantially increased the probability of complete corneal healing at 8 weeks, with a pooled RR of 1.84 (95% CI 1.34-2.52; Conclusion: Cenegermin is an effective and well-tolerated, disease-modifying therapy for moderate to severe NK. It nearly doubles the likelihood of complete corneal healing and represents an important addition to the therapeutic options available for this debilitating condition. Larger, independently funded trials with longer follow-up are warranted to confirm these findings and to establish its position within the treatment algorithm.
