Psoralidin Stimulates Expression of Immediate-Early Genes and Synapse Development in Primary Cortical Neurons.
Article in Neurochemical research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 9 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
Upon synaptic stimulation and glutamate release, glutamate receptors are activated to regulate several downstream effectors and signaling pathways resulting in synaptic modification. One downstream intracellular effect, in particular, is the expression of immediate-early genes (IEGs), which have been proposed to be important in synaptic plasticity because of their rapid expression following synaptic activation and key role in memory formation. In this study, we screened a natural compound library in order to find a compound that could induce the expression of IEGs in primary cortical neurons and discovered that psoralidin, a natural compound isolated from the seeds of Psoralea corylifolia, stimulated synaptic modulation. Psoralidin activated mitogen-activated protein kinase (MAPK) signaling, which in turn induced the expression of neuronal IEGs, particularly Arc, Egr-1, and c-fos. N-methyl-D-aspartate (NMDA) receptors activation and extracellular calcium influx were implicated in the psoralidin-induced intracellular changes. In glutamate dose-response curve, psoralidin shifted glutamate EC
