Effect of Methylprednisolone on Ischemic Brain Edema After Temporary Occlusion of the Middle Cerebral Artery in Rats.
Article in Physiological research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We studied the effect of Methylpredisolone (MP) on ischemic brain edema after temporary occlusion of the middle cerebral artery for 90 min (MCAo90). We verified the presence of ischemic edema by determining the brain water content (BWC) by measuring dry/wet weight and by examining MRI - T2-weighted imaging, T2 relaxation times and apparent diffusion coefficient (ADC). In another group, animals were administered MP intraperitoneally 30 min after MCAo90, followed by 24 h reperfusion (MCAoMP). Edema changes were documented by the same MRI examinations. A statistically significant increase in BWC was found between the post-MCAo90 group of animals and the intact animals, demonstrating the presence of edema in the former group. A statistically significant increase in ADC was observed in the MCAo group, indicating the presence of vasogenic edema. A statistically significant difference was demonstrated between the MCAo and MCAoMP groups, with no statistically significant difference between the CG and MCAoMP groups, demonstrating a reduction in ischemic brain swelling after MP administration. The main effect of MP on ischemic brain edema is attributed to its antioxidant capacity. It can be assumed that this capacity of MP, with its complex impact on cellular metabolism, affects the movement of water in the brain and reduces ischemic brain edema.
