The Dopamine Transporter Is a New Target for Ischemic Stroke.
Article in CNS neuroscience & therapeutics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
aimsDopamine transporter (DAT) can regulate DA homeostasis and has been implicated in many nervous system diseases. Whether DAT is involved in the protection against ischemic stroke is unclear.
methodsIn vivo microdialysis measurements of DA were recorded in the ischemic penumbral area of mice with middle cerebral artery occlusion (MCAO). DAT coding gene, Slc6a3 mutation, and DAT overexpression animals were performed MCAO. Madopar (compound formulation of levodopa) and nomifensine (DA reuptake inhibitor) were administered in MCAO animals. Brain slices were prepared in Slc6a3 mutation or wild-type (WT) animals with MCAO to record miniature excitatory postsynaptic currents (mEPSCs) and miniature inhibitory postsynaptic currents (mIPSCs). The effects of DA and its dopamine-1 receptor (D
resultsMCAO caused a prominent increase in DA. Slc6a3 mutation significantly attenuated the ischemic injury, whereas DAT overexpression aggravated this injury. Both nomifensine and madopar protected against brain injury. Slc6a3 mutation and DA restored the disturbance of mEPSCs and mIPSC, and protected against neuron death, which was abolished by SCH-23390.
conclusionDAT inhibition might be explored as a strategy for ischemic stroke prevention. DA and D
