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

objectivePost-traumatic epilepsy (PTE) is a serious complication of traumatic brain injury (TBI). This study is designed to determine the feasibility of using multiparametric MRI endpoints to predict differences in seizure susceptibility after experimental TBI.

methodsMRI imaging and behavioral measurements were performed at multiple time points after lateral fluid percussion injury (FPI) in rats. Seizure susceptibility was determined by video-electroencephalogram (EEG) monitoring and off-line signal analysis after chemoconvulsant challenge.

resultsMultiple MRI endpoints, including measures of injury-related brain swelling (normalized interhemispheric volume difference, NIVD) and T1-weighted signal change with contrast enhancement (a measure of blood-brain barrier disruption, BBBD), reliably distinguished between injured and sham-injured animals at 72 hours after injury. ADC (apparent diffusion coefficient) values (a measure of water diffusivity) in injured cortex at 72 hours and 1 week after injury, BBBD in injured cortex at 72 hours after injury and NIVD at 72 hours after injury were significantly correlated with EEG-based measures of seizure susceptibility to chemoconvulsant challenge at 3 months after injury.

conclusionsThe correlations between our MRI quantitative endpoints and EEG-based measures of seizure susceptibility to chemoconvulsant challenge in injured animals versus sham-injured animals support the feasibility of these MRI endpoints as potential biomarkers for post-traumatic epileptogenesis.
