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

Evidence has shown the therapeutic potential of isoflurane (ISO) in cerebral stroke. The present study investigated the mechanism of ISO on vascular endothelial growth factor (VEGF) and CD34 expression in a rat model of stroke. Transient focal cerebral ischemia was established by middle cerebral artery occlusion (MCAO) for 1 h followed by reperfusion for 24 h in rats. ISO was administered for 1.5 h when the reperfusion was initiated. Neurologic deficit scores, infarct volumes, HE staining, Nissl staining, and TUNEL staining were evaluated at 24 h after reperfusion. The levels of transforming growth factor (TGF)-β2, Smad3, p-Smad3, VEGF, and CD34 proteins were detected by immunofluorescence (IF) staining and Western blot assay. Administration of ISO significantly reduced the neurologic deficit scores, infarct volumes, and damaged and apoptotic cells after cerebral ischemia/reperfusion (I/R) injury (P < 0.05). Meanwhile, ISO post-conditioning significantly increased the expression levels of TGF-β2, p-Smad3, VEGF, and CD34 (P < 0.05), whereas the expression of Smad3 showed no difference (P > 0.05). However, Pirfenidone, a TGF-β2 inhibitor, decreased the expression levels of TGF-β2, p-Smad3, VEGF, and CD34 (P < 0.05). Moreover, the protective effects of ISO post-conditioning were negated by the inhibitor. The present study indicated that ISO attenuates brain damage by activating the TGF-β2/Smad3 signaling pathway and increasing the protein expression of VEGF and CD34 in the rat MCAO model.
