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

Peripheral nerve injury (PNI) is a common disease, which results in a partial or total loss of motor, sensory and autonomic functions, leading to a decrease in quality of life. Schwann cells play a vital role in maintaining the peripheral nervous system and in injury and repair. Using immunohistochemistry, Western blot, calcium assay and bromodeoxyuridine (BrdU) proliferation assay, the present study clearly demonstrated that P2X7 receptors (R) were expressed in myelinating and non-myelinating Schwann cells in longitudinal sections of sciatic nerves. After sciatic nerve injury (SNI), P2X7R expression in Schwann cells of injured sciatic nerves was significantly up-regulated during the early days of SNI. Double immunofluorescence of proliferating cell nuclear antigen (PCNA) and P2X7R implied that P2X7R may be involved in proliferation of Schwann cells. Further experiments on primary cultures of Schwann cells showed that P2X7R are functionally expressed in Schwann cells of rat sciatic nerves; ATP via P2X7R can promote Schwann cell proliferation, possibly via the MAPK/ERK intracellular signalling pathway. Other possible roles of P2X7R on Schwann cells are discussed.
