Overcoming Barriers to Axonal Regeneration in Spinal Cord Injury: Mechanistic Insights and Therapeutic Frontiers.
Review in CNS neuroscience & therapeutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSpinal cord injury (SCI) is a devastating central nervous system disorder that often causes permanent neurological deficits, while effective disease-modifying therapies remain lacking. Functional recovery depends on axonal regeneration, which is limited by the inhibitory post-injury microenvironment and the reduced regenerative capacity of mature neurons.
methodsThis review summarizes the mechanisms underlying axonal regeneration failure after SCI and discusses recent advances in regenerative strategies and their translational progress.
resultsCurrent evidence indicates that impaired axonal regeneration results from both extrinsic inhibitory factors and intrinsic neuronal growth limitations. Regenerative strategies, including modulation of glial scar dynamics, degradation of inhibitory extracellular matrix components, reconstruction of a permissive regenerative microenvironment, stem cell transplantation, biomaterial scaffolds, activation of intrinsic growth programs, and neuromodulation, have shown promising effects in preclinical studies. However, clinical translation remains limited by challenges related to therapeutic timing, delivery efficiency, biosafety, scalability, and insufficient clinical evidence.
conclusionsFuture SCI repair will likely require combinatorial strategies targeting multiple regenerative mechanisms while improving clinical feasibility. This review integrates current mechanistic and translational advances to support the development of more effective regenerative therapies for SCI.
