Obesity and mental health improvement following nutritional education focusing on gut microbiota composition in Japanese women: a randomised controlled trial.
Trial report in European journal of nutrition, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 28 papers, 3 of them syntheses that pooled 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.
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
purposeGut microbiota composition was supposedly related to obesity and psychological factors. We examined the effects of a nutritional education intervention focusing on gut microbiota composition on obesity and psychological factors among obese women.
methodsForty-four obese Japanese women aged 40 or older were randomly assigned to either an intervention group (n = 22) or control group (n = 22). The intervention consisted of a 20-min dietary lecture and a 10-min counselling session by registered dieticians, every 2 weeks for eight consecutive weeks. Body weight, height, waist circumference, food frequency, and gut microbiota composition were measured, and self-rated health and psychological factors were scored before and after the intervention.
resultsAll participants completed the 8 week program. After the intervention, dietary fibre intake (p < 0.01), frequency of vegetable consumption (p = 0.020), and frequency of milk and milk product consumption (p < 0.01) increased significantly in the intervention group compared with the control group. Body weight and body mass index (BMI; p < 0.001), waist circumference (p < 0.01), and the depression scale score (p < 0.01) decreased significantly, while significant improvements were found in self-rated health (p = 0.045) and microbiome diversity (p < 0.01).
conclusionNutritional education focusing on gut microbiota composition may improve obesity and psychological factors in obese women.
