How the ghrelin receptor recognizes the acyl-modified orexigenic hormone.
Review in Frontiers in molecular neuroscience, 2025. 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
Ghrelin, discovered in 1999 as an endogenous ligand of the growth hormone secretagogue receptor (now known as the ghrelin receptor), is a peptide hormone with diverse physiological activities, such as stimulation of growth hormone release, increased appetite, fat accumulation, thermoregulation, and cardioprotection. As a distinctive feature, ghrelin needs to undergo octanoylation, a specific acyl modification, to exert its biological activities. Although the ghrelin receptor specifically recognizes this modification, the underlying molecular mechanism had remained unclear for decades. Recent advancements in structural biology have facilitated the elucidation of this recognition mechanism 25 years after ghrelin's discovery. This review highlights the structural basis of ghrelin octanoylation, particularly emphasizing the mechanism by which the ghrelin receptor recognizes this acyl-modified hormone.
