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

aimsEmerging data suggest more young women than men are prescribed weight loss pharmacotherapies targeting the glucagon-like peptide-1 receptor (GLP-1R). However, preclinical literature has largely used male animals to characterize the neural mechanisms underlying the weight loss abilities of GLP-1R agonists (GLP-1RAs), highlighting a need for female-specific investigations. Recently, we described data pointing to the female estrous cycle as a possible moderator of GLP-1RA's effects in rats. Expression of brainstem Glp1r and the GLP-1 precursor gene, Gcg, increased during two estrous phases, proestrus and estrus (P/E), compared to males and compared to other phases, metestrus and diestrus (M/D). On this basis, we hypothesized that the weight-reducing effects of GLP-1RAs may be potentiated during P/E. MATERIALS AND

methodsIn separate experiments, we determined whether timing administration of acute liraglutide or chronic semaglutide to either P/E or M/D would moderate food intake and weight loss in female rats maintained on a high fat diet. We also used qPCR to explore estrous cycle-dependent variation in Glp1r within widely distributed nuclei relevant to energy balance control.

resultsGLP-1RA administration during P/E, compared to M/D, enhanced the intake-suppressive effects of liraglutide and semaglutide. Moreover, semaglutide administered only during P/E led to greater body weight loss compared to M/D-administered semaglutide. We also observed greater Glp1r expression in P/E compared to M/D in multiple nuclei.

conclusionsGLP-1RAs administered in P/E lead to significantly greater body weight loss via reduction in food intake. Collectively, these data may have translational implications for the timing of GLP-1RA administration across the menstrual cycle.
