Plant-based dietary indices association with appetite, appetite regulating peptides and gut microbiota in healthy women: a cross-sectional study.

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
purposePlant-based diets are associated with improved appetite regulation. Moreover, gut microbiota has been linked to appetite. The present study aims to determine the association between plant-based dietary indices (PDIs) and appetite-regulating peptides (fasting level of Leptin, GLP-1, and ghrelin) and gut microbiota profile in healthy women. Furthermore, the potential covariate role of gut microbiota in the association between PDIs and appetite is investigated.
methodsThis cross-sectional study was conducted on 91 healthy women (18-50 years). Body composition, anthropometric indices, dietary intake, PDIs, subjective appetite, appetite-regulating peptides (fasting level of leptin, GLP-1, and ghrelin), physical activity, sleep quality, and gut microbiota profile were evaluated.
resultsThere was a significant inverse association between scores of PDI and healthful plant-based dietary index (hPDI) with leptin and IL-6 (p < 0.05). A higher hPDI was associated with a lower GLP-1 concentration (p = 0.04). Additionally, uPDI (unhealthful plant-based diet index) was inversely associated with satiety (p = 0.02) and positively associated with hunger (p = 0.02). Moreover, higher PDI was associated with higher Prevotella abundance (p = 0.01). Our findings suggest that Firmicutes and the Firmicutes/Bacteroidetes ratio might be involved in the associations between hPDI and both leptin and GLP-1 levels. Additionally, A. muciniphila may play a role in the association between hPDI and GLP-1 levels as a relevant microbial factor. However, the potential mediating effects of these bacteria should be investigated in future studies.
conclusionWe indicated an inverse association between higher PDI and hPDI scores with appetite-related hormones and IL-6. Moreover, higher uPDI was related to appetite sensation and a higher PDI score increased the abundance of Prevotella. The association between hPDI scores and appetite-regulating hormones may be influenced by the gut microbiota. Considering lower levels of fasting GLP-1 in relation with hPDI, it appears further evaluation of the postprandial state of GLP-1 in cohort studies or intervention trials is also warrented to better elucidate their association.
