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
Stromal cell-derived factor-1 alpha (SDF-1a) or CXCL12 is an important cytokine with multiple functions in the brain during development and in adulthood. The inflammatory response initiated by spinal cord injury (SCI) involves the processing of interleukin-1beta (IL-1ß) and IL-18 mediated by caspase-1 which is under the control of an intracellular multiprotein complex termed inflammasome. Using an SCI rat model, we found improved functional long-term recovery which is paralleled by a reduction of apoptosis after intrathecal treatment with SDF-1a. An intriguing aspect is that SDF-1a changed the number of neuroinflammatory cells in the damaged area. We further examined the cellular localization and sequential expression of several inflammasomes during SCI at 6 h, 24 h, 3 days, and 7 days as well as the role of SDF-1a as a regulatory factor for inflammasomes. Using 14-week old male Wistar rats, spinal cord contusion was applied at the thoracic segment 9, and animals were subsequently treated with SDF-1a via intrathecal application through an osmotic pump. SCI temporally increased the expression of the inflammasomes NLRP3, ASC, the inflammatory marker tumor necrosis factor-a (TNF-a), interleukin-1ß (IL-1β) and IL-18. SDF-1a significantly reduced the levels of IL-18, IL-1b, TNF-a, NLRP3, ASC, and caspase-1. Immunofluorescence double-labeling demonstrated that microglia and neurons are major sources of the ASC and NLRP3 respectivley. Our data provide clear evidence that SCI stimulates a complex scenario of inflammasome activation at the injured site and that SDF-1a-mediated neuroprotection presumably depends on the attenuation of the inflammasome complex.
