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.
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
Although studies concerning blast-related traumatic brain injury (bTBI) have demonstrated the significance of diffuse axonal injury (DAI), no standard models for this type of injury have been widely accepted. The present study investigated a mechanism of inducing DAI through real blast injury, which was achieved by performing instantaneous high-speed swinging of the rat head, thus establishing a stable animal model of blast DAI. Adult Sprague-Dawley rats weighing 150±10 g were randomly divided into experimental (n=16), control (n=10) and sham control (n=6) groups. The frontal, parietal and occipital cortex of the rats in the experimental group were exposed, whereas those of the control group were unexposed; the sham control group rats were anesthetized and attached to the craniocerebral blast device without experiencing a blast. The rats were subjected to craniocerebral blast injury through a blast equivalent to 400 mg of trinitrotoluene using an electric detonator. Biomechanical parameters, and physical and behavioural changes of the sagittal head swing were measured using a high-speed camera. Magnetic resonance imaging (MRI) scans were conducted at 2, 12, 24 and 48 h after craniocerebral injury, only the experimental group indicated brain stem injury. The rats were sacrificed immediately following the MRI at 48 h for pathological examination of the brain stem using haematoxylin and eosin staining. The results indicated that 14 rats (87.5%) in the experimental group exhibited blast DAI, while no DAI was observed in the control and sham control groups, and the difference between the groups was significant (P<0.05). The present results indicated that this experimental design may serve to provide a stable model of blast DAI in rats.
