Learning against the Background of DNA Methyltransferase Inhibition Leads to the Formation of Memory That Is Resistant to Reactivation and Impairment.
Article in Bulletin of experimental biology and medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The involvement of DNA methylation in the mechanisms of formation of conditioned food aversion memory was studied on Helix lucorum snails. The dynamics of aversion formation in snails injected with DNA methyltransferase inhibitor RG108 did not differ from that in control snails. The memory was retained for more than one month after training following RG108 injection and the duration of memory persistence did not differ from that in control animals. However, the characteristics of memory in control and experimental snails differed significantly. In control snails, injections of glutamate NMDA-receptor antagonist or protein synthesis inhibitor before memory retrieval caused disorders in the memory reconsolidation and development of amnesia 2 days after training. By contrast, injections of these substances before retrieval to snails trained against the background of RG108 treatment caused no memory disorders. We hypothesized that inhibition of DNA methylation processes led to the formation of strong memory, not reactivated after retrieval and not transformed into a labile state sensitive to amnesic agents.
