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
The glial scar that forms at the site of injury after spinal cord injury (SCI) is an important physical and biochemical barrier that prevents axonal regeneration and thus delays functional recovery. Ski is a multifunctional transcriptional co-regulator that is involved in a wide range of physiological and pathological processes in humans. Previous studies by our group found that Ski is significantly upregulated in the spinal cord after in vivo injury and in astrocytes after in vitro activation, suggesting that Ski may be a novel molecule regulating astrocyte activation after spinal cord injury. Further studies revealed that knockdown or overexpression intervention of Ski expression could significantly affect the proliferation and migration of activated astrocytes. To further verify the effect of knockdown of Ski expression in vivo on glial scar formation and neurological function after spinal cord injury, we prepared a rat spinal cord injury model using Allen's percussion method and used lentivirus as a vector to mediate the downregulation of Ski in the injured spinal cord. The results showed that knockdown of Ski expression after spinal cord injury significantly suppressed the expression of glial fibrillary acidic protein (Gfap) and vimentin, hallmark molecules of glial scarring, and increased the expression of neurofilament protein-200 (Nf-200) and growth-associated protein (Gap43), key molecules of axon regeneration, as well as Synaptophysin, a key molecule of synapse formation expression. In addition, knockdown of Ski after spinal cord injury also promoted the recovery of motor function. Taken together, these results suggest that Ski is able to inhibit the expression of key molecules of glial scar formation, and at the same time promotes the expression of molecules that are markers of axonal regeneration and synapse formation after spinal cord injury, making it a potential target for targeted therapy after spinal cord injury.
