1 · What the graph read from it

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.

2 · The registry

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

Brachial plexus injury is frequent after traffic accident in adults or shoulder dystocia in newborns. Whereas surgery can restore arm movements, therapeutic options are missing for sensory defects. Dorsal root (DR) ganglion neurons convey sensory information to the central nervous system (CNS) through a peripheral and a central axon. Central axons severed through DR section or avulsion during brachial plexus injury inefficiently regenerate and do not reenter the spinal cord. We show that a combination of microsurgery and gene therapy circumvented the functional barrier to axonal regrowth at the peripheral and CNS interface. After cervical DR section in rats, microsurgery restored anatomical continuity through a nerve graft that laterally connected the injured DR to an intact DR. Gene transfer to cells in the nerve graft induced the local release of neurotrophin-3 (NT-3) and glial cell line-derived neurotrophic factor (GDNF) and stimulated axonal regrowth. Central DR ganglion axons efficiently regenerated and invaded appropriate areas of the spinal cord dorsal horn, leading to partial recovery of nociception and proprioception. Microsurgery created conditions for functional restoration of DR ganglion central axons, which were improved in combination with gene therapy. This combination treatment provides means to reduce disability due to somatosensory defects after brachial plexus injury.
