Brain ischemic preconditioning protects against moderate, not severe, transient global cerebral ischemic injury.
Article in Metabolic brain disease, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Ischemic preconditioning (IPC) in the brain increases ischemic tolerance to subsequent ischemic insults. In this study, we examined whether IPC protects neurons and attenuates microgliosis or not in the hippocampus following severe transient global cerebral ischemia (TCI) in gerbils. Gerbils were assigned to 8 groups; 5- and 15-min sham operated groups, 5-min and 15-min TCI operated groups, IPC plus 5- and 15-min sham operated groups, and IPC plus 5- and 15-min TCI operated groups. IPC was induced by subjecting animals to 2-min transient ischemia 1 day before 5-min TCI for a typical transient ischemia and 15-min TCI for severe transient ischemia. Neuronal damage was examined by cresyl violet staining and Fluoro-Jade B histofluorescence staining. In addition, microglial activation was examined using immunohistochemistry for Iba-1 (a marker for microglia). Delayed neuronal death and microgliosis was found in the CA1 alone in the 5-min TCI operated group at 5 days post-ischemia, and, in the 15-min TCI operated group, neuronal death and microgliosis was shown in all CA areas (CA1-3) and the dentate gyrus. IPC displayed neuroprotection and attenuated microglial activation in the 5-min TCI operated group. However, in the 15-min TCI operated group, IPC did not show neuroprotection and not attenuate microglial activation. Our present findings indicate that IPC hardly protect against severe transient cerebral ischemic injury.
