Effect of Lycium barbarum polysaccharide on functional recovery after decompression in a rat model of degenerative cervical myelopathy.
Article in Asian spine journal, 2025. 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
STUDY
designAnimal study. PURPOSE: To investigate the effects of Lycium barbarum polysaccharide (LBP) on functional recovery following decompressive surgery in a rat model of cervical spondylotic myelopathy (CSM). OVERVIEW OF LITERATURE: Surgical decompression halts the progression of CSM, but may leave residual neurologic deficits. LBP, derived from wolfberry, has been shown to modulate macrophage polarization and exert neuroprotective effects in acute spinal cord injury. We hypothesized that LBP would enhance functional recovery after surgical decompression in a rat model of CSM.
methodsFemale Sprague-Dawley rats with induced chronic cervical spinal cord compression were randomly assigned to the following groups: (1) LBP alone; (2) decompression alone; (3) decompression+LBP; (4) no treatment; and (5) sham surgery. Decompression was performed 4 weeks after compression. Outcomes were assessed using neurobehavioral tests, electrophysiology, and histological/immunohistochemical analyses.
resultsBaseline spinal cord injury severity was comparable across groups, as confirmed by electrophysiological studies. At 8 weeks postsurgery, rats in the decompression+LBP group showed significantly greater recovery of hindlimb function compared with rats in the decompression alone group. Improvements in somatosensory evoked potential and motor evoked potential latency and amplitude were also more pronounced in the decompression+LBP group. Histological analyses demonstrated reduced myelin vacuolation and increased myelin density with LBP treatment.
conclusionsThis study provides the first evidence that LBP derived from Chinese herbal medicine enhances neurological and functional recovery when combined with decompression in a rat model of CSM. These findings support further clinical investigation of LBP as an adjunctive therapy in patients with CSM.
