Cyclo (MQCNS) has the potential to treat ischemic stroke.
Article in Neural regeneration research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 previously found that monocyte locomotion inhibitory factor has a neuroprotective effect on ischemic brain injury during the acute phase of stroke. Therefore, we modified the structure of an anti-inflammatory monocyte locomotion inhibitory factor peptide to construct an active cyclic peptide-Cyclo (MQCNS) (LZ-3)-and investigated its effects on ischemic stroke. In this study, we established a rat model of ischemic stroke by occluding the middle cerebral artery and then administered LZ-3 (2 or 4 mg/kg) via the tail vein for 7 consecutive days. Our results showed that LZ-3 (2 or 4 mg/kg) substantially decreased infarct volume, reduced cortical nerve cell death, improved neurological function, reduced cortical and hippocampal injury, and decreased the levels of inflammatory factors in the blood and brain tissues. In a well-differentiated, oxygen-glucose deprivation/reoxygenation-induced BV2 cell model of post-stroke, LZ-3 (100 μM) inhibited the JAK1-STAT6 signaling pathway. LZ-3 regulated microglia/macrophage polarization from the M1 to the M2 type and inhibited microglia/macrophage phagocytosis and migration via the JAK1/STAT6 signaling pathway. To conclude, LZ-3 regulates microglial activation by inhibiting the JAK1/STAT6 signaling pathway and improves functional recovery post-stroke.
