Posterior Reversible Encephalopathy Syndrome (PRES) following blood transfusion in a polytrauma victim, an atypical occurrence.
Article in Turkish journal of emergency medicine. 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
Posterior reversible encephalopathy syndrome (PRES) is a neuroradiological syndrome, clinically present by impaired consciousness, headache, visual disturbances, and seizures, and radiologically brain edema. Cases of PRES induced by blood transfusion are rarely documented. We report this case to increase the awareness of treating physicians for the possible complications of rapid blood transfusion. A 29-year-old man presented with polytrauma and was in hemorrhagic shock. He was transfused with multiple transfusions. Later, he was found to have quadriplegia with minimal movement of fingers in the left hand. His computed tomography showed cerebral edema in multiple cerebral regions. We propose that the etiology in this case is that rapid blood transfusion induced acute rise in hemoglobin which led to PRES. The influences of blood transfusion on blood flow, blood viscosity, and endothelial dysfunction lead to blood-brain barrier dysfunction, which can result in PRES.
