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
mRNA translation initiation plays a critical role in learning and memory. The eIF4F complex, composed of the cap-binding protein eIF4E, ATP-dependent RNA helicase eIF4A, and scaffolding protein eIF4G, is a pivotal factor in the mRNA translation initiation process. eIF4G1, the major paralogue of the three eIF4G family members, is indispensable for development, but its function in learning and memory is unknown. To study the role of eIF4G1 in cognition, we used an eIF4G1 haploinsufficient (eIF4G1-1D) mouse model. The axonal arborization of eIF4G1-1D primary hippocampal neurons was significantly disrupted, and the mice displayed impairment in hippocampus-dependent learning and memory. Translatome analysis showed that the translation of mRNAs encoding proteins of the mitochondrial oxidative phosphorylation (OXPHOS) system was decreased in the eIF4G1-1D brain, and OXPHOS was decreased in eIF4G1-silenced cells. Thus, eIF4G1-mediated mRNA translation is crucial for optimal cognitive function, which is dependent on OXPHOS and neuronal morphogenesis.
