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

Ferric chloride-induced distal middle cerebral artery occlusion (MCAO) model of stroke was described in mice several years ago, however it lacked in-depth evaluation of the post-stroke functional outcomes in the animals. In this study, we reproduced the recently developed model and expanded its characterization by thorough evaluation of blood supply, cerebral infarction, and motor function in adult male and female mice up to 14 days after stroke. Our observations indicate near complete interruption of blood flow in the distal MCA shortly after application of 20 % ferric chloride over the artery through a cranial window, which remained occluded for at least 4 h. As expected, infarction of the brain tissue, documented by TTC and hematoxylin stains, was restricted to the cerebral cortex. We also systematically evaluated motor impairment of the animals in this model. For this, a series of studies were carried out in male and female mice up to 14 days after stroke, and motor function was assessed in cylinder and grid-walking tests in blinded manner. Contrary to our expectations, the results of both motor tests indicated minor, transient motor deficit in mice after stroke. Based on these observations, we conclude that the mouse ferric chloride-induced distal MCAO model is likely not suitable for proof-of-concept and preclinical studies where motor function is an important outcome measure.
