Recovery of independent ambulation after complete spinal cord transection in the presence of the neuroprotectant polyethylene glycol in monkeys.

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
Objective: Despite the conventional belief that motor function and sensation distal to the site of a complete spinal cord transection are irretrievable, our research has demonstrated significant motor recovery in mice, rats, and dogs by applying polyethylene glycol (PEG) topically via a syringe directly to the contact interface of transected spinal cord. However, before implementing this technology in human subjects, validating PEG's efficacy and enduring impact through experimentation on non-human primates is imperative. Methods: Two 4-year-old female Macaca fascicularis monkeys underwent complete dorsal cord transection at T10. Postoperative behavioral assessment, electrophysiologic monitoring, and neuroimaging examinations were recorded, and tissues were obtained for histological examination at the end of study. Results: The monkey whose spinal cord had been fully transected in the presence of PEG developed useful recovery already at 3 months and near-complete recovery of motor function in the hind-limbs at 18 months. The control animal without PEG remained paralyzed. Cortical somatosensory evoked potentials recovered postoperatively only in PEG-treated monkey vs none in the control. Diffusion tensor imaging showed re-establishment of continuity of the white matter in PEG-treated monkey, but not in the control. Moreover, histology revealed intact neuronal bodies, axons, and myelin tissue at the spinal cord transection site in PEG-treated monkey only. Conclusion: This report suggests that in primates, an acutely transected spinal cord can be re-fused in the presence of PEG with restoration of neural continuity and functional recovery of motor activity distal to the site of transection.
