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

Astrocytes play an active and important role in the pathophysiology of cerebral ischemia. We have previously shown that mature hipppocampal astrocytes functionally express two-pore domain K(+) channel TREK-1, which significantly contributes to the passive conductance and help to set the negative resting membrane potential essential for the optimal operation of some astrocytic homeostatic functions. However, its expression under ischemic conditions remains to be determined. In this study, we examined the expression of TREK-1 in rat brain under physiological and focal ischemia conditions. The results show that TREK-1 was broadly expressed on astrocytes and neurons in the cortex, CA1 region of hippocampus. After middle cerebral artery occlusion induced focal ischemia, the TREK-1 expression was significantly increased at days 3, 7 and 30 following reperfusion, which correlated with reactive astrogliosis in the cortex and hippocampus. Cultured cortical astrocytes also express TREK-1. TREK-1 inhibitor quinine inhibited the proliferation of astrocytes exposed to hypoxia condition. These data provide evidence showing the astrocytic TREK-1 involvement in ischemia pathology.
