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

(1S,2E,4R,6R,-7E,11E)-2,7,11-cembratriene-4,6-diol (4R) is a precursor to key flavor ingredients in leaves of Nicotiana species. The present study shows 4R decreased brain damage in rodent ischemic stroke models. The 4R-pretreated mice had lower infarct volumes (26.2±9.7 mm3) than those in control groups (untreated: 63.4±4.2 mm3, DMSO: 60.2±14.2 mm3). The 4R-posttreated rats also had less infarct volumes (120±65 mm3) than those in the rats of the DMSO group (291±95 mm3). The results from in vitro experiments indicate that 4R decreased neuro2a cell (neuroblastoma cells) apoptosis induced by oxygen-glucose deprivation (OGD), and improved the population spikes' (PSs) recovery in rat acute hippocampal slices under OGD; a phosphatidylinositol 3-kinase (PI3K) inhibitor, wortmannin, abolished the effect of 4R on PSs recovery. Furthermore, 4R also inhibited monocyte adhesion to murine brain-derived endothelial (bEND5) cells and upregulation of intercellular adhesion molecule-1(ICAM-1) induced by OGD/reoxygenation (OGD/R), and restored the p-Akt level to pre-OGD/R values in bEND5 cells. In conclusion, the present study indicates that 4R has a protective effect in rodent ischemic stroke models. Inhibition of ICAM-1 expression and restoration of Akt phosphorylation are the possible mechanisms involved in cellular protection by 4R.
