Gut flora influences the hypothalamic-gonadal axis to regulate the pathogenesis of obesity-associated precocious puberty.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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 prevalence of obesity-associated precocious puberty is gradually increasing, but the relationship between gut flora and obesity-associated precocious puberty remains unclear.We analysed the gut flora characteristics of a clinical sample of 30 girls aged 5-8 years using 16s rRNA sequencing. An obesity rat model and a rat model of gut flora transplantation were also constructed. Body weight, body length, abdominal girth, food intake, vulva opening time, and gonadal index were monitored. The secretion levels of estradiol (E2), total cholesterol (TC), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and thyroglobulin (Tg) were analyzed by ELISA. In addition, ovarian and uterine development was observed by HE staining. The mRNA and protein levels of kisspeptin-1 (Kiss-1) and gonadotropin-releasing.We found that the relative abundance of Dialister, Bacteroides, Bifidobacterium, Collinsella, and Romboutsia may be associated with obesity-associated precocious puberty. Obesity promotes gonadal development, and the gut flora of patients with obesity and obesity-associated precocious puberty regulated the gene and protein expression of Kiss-1 and GnRH, promoting precocious puberty and hypothalamic-gonadal axis hormone secretion in rats. In contrast, probiotic intervention slowed gonadal development, reduced hormone secretion, and attenuated hypothalamic-gonadal axis activity. Gut flora promoted obesity-associated precocious puberty by influencing the hypothalamic-gonadal axis, and probiotics have a therapeutic and preventive role in obesity-associated precocious puberty, which may be associated with the Kiss-1/GnRH pathway. These findings may provide some new strategies for clinical treatment and prevention of obesity-associated precocious puberty in girls.
