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

MicroRNAs (miRNAs) play a key role in different nervous system diseases. We sought to determine the role of miRNAs in isoflurane-induced learning and memory impairment in aged rats. Male Sprague-Dawley (SD) rats of 18 month were randomly assigned to control group (exposed to mock anesthesia), 2-hour group and 6-hour group (exposed to 2% isoflurane for 2 and 6 hours respectively). By Morris Water Maze, 6-hour group showed impaired learning and memory ability while 2-hour group not. As shown by miRNA array, control group and 2-hour group showed a similar miRNA expression profile. And 38 miRNAs are differently expressed in 6-hour group compared to the other 2 groups, including 21 up-regulated miRNAs and 17 down-regulated miRNAs. And 4 of the differentially expressed miRNAs were validated independently by qRT-PCR. Let-7d was downregulated in 6-hour group. Additionally, we demonstrated that amyloid precursor protein (APP) was a direct target of let-7d by Fluorescent report assay. Increased expression of APP and amyloid-β (Aβ) were found in the hippocampi of 6-hour group. Downregulation of let-7d might contribute to isoflurane-induced learning and memory impairment through upregulating its target APP, and increasing the production of Aβ subsequently.
