1 · What the graph read from it

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.

2 · The registry

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

In rodents, glucagon-like peptide-1 (GLP-1)-positive neurons within the caudal medulla respond to a broad array of interoceptive signals that suppress food intake and drive the hypothalamic-pituitary-adrenal stress axis. The collective results of experiments utilizing cFos to identify activated neurons in rats and mice indicate that GLP-1 neurons are consistently activated by stimuli that present actual or anticipated threats to bodily homeostasis. The distribution of GLP-1-positive neurons in the human brain is unreported. The present study identified GLP-1-positive neurons and mapped their distribution within the caudal medulla in two adult human subjects (one female, one male). The goal of the study was to obtain structural evidence with which to challenge the general hypothesis that functions ascribed to GLP-1 neurons in rodent species may reflect parallel functions that exist in humans. In both human subjects, GLP-1-immunopositive neurons were located within the dorsal medullary region containing the caudal (visceral) nucleus of the solitary tract and in the nearby medullary reticular formation, similar to the distribution of GLP-1 neurons in rats, mice, and Old World monkeys. Quantitative analysis indicates the presence of approximately 6.5-9.3 K GLP-1-positive neurons bilaterally within the human caudal medulla. It will be important in future studies to map the distribution of GLP-1-positive fibers and terminals within higher regions of the human brain, to improve our understanding of how central GLP-1 signaling pathways might influence stress responsiveness, energy balance, and other physiological and behavioral functions.
