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

The intestinal microbiota is shaped by fiber-rich ingredients, such as unripe banana flour (UBF), high in resistant starch (RS). We investigated the effects of RS-rich UBF and inulin on gut microbiota and intestinal function in a double-blind, randomized, placebo-controlled pilot trial. Forty-eight healthy adults consumed maltodextrin (control), inulin, or UBF three times weekly for six weeks. Microbiota composition and function were analyzed using 16S rRNA gene sequencing and PICRUSt, alongside fecal short-chain fatty acids, blood biochemistry, and gastrointestinal parameters. We observed two microbiota clusters at baseline, one Prevotella-rich (P) and one Bacteroides-rich (B), with distinct responses to the interventions. Only cluster P subjects consuming UBF showed significant global microbiota shifts (weighted Unifrac Beta diversity, PERMANOVA p = 0.007) and major functional changes (533 KEGG orthologs, FDR < 0.05). Inulin produced modest modulation (19 KOs) on cluster P, and no effects were observed on cluster B. RS-rich UBF modulated gut microbiota in a composition-dependent manner, supporting the potential of microbiota-based stratification to improve dietary fiber interventions.
