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

backgroundThis study aimed to compare the gut microbiome (GM) composition, serum inflammatory markers and faecal short-chain fatty acids among individuals with type 1 and type 2 diabetes mellitus (DM) and healthy controls.

methodsThis case-control study examined 49 subjects with type 2 DM, 21 with type 1 DM and 40 healthy controls. Blood and faecal samples were collected. Serum inflammatory markers, including CRP, IL-1β, IL-6, TNF-α and IFN-γ, were measured using enzyme-linked immunosorbent assays (ELISA). Bacterial populations were quantified using RT-qPCR and NGS. Faecal metabolites were analysed using gas chromatography.

resultsSimpson's alpha diversity was higher among types 1 and 2 DM than in the control. The frequency of the bacterial genera Gemmiger, Dorea, Collinsella, Escherichia/Shigella, Dialister, Coprococcus, Achromobacter, Intestinimonas and Allisonella in type 2 DM was higher than in the control, and the frequency of the genera Romboutsia and Clostridium was decreased in type 2 DM. The frequency of the Prevotella, Bacteroides and Faecalibacterium genera in type 1 DM was lower than in the other groups. Acetate, propionate and butyrate levels were significantly higher in type 2 DM patients compared to the other groups. Participants with diabetes had significantly higher hs-CRP, IL1-β, TNF, IL-6 and IFG levels compared to the controls. Compared to healthy controls, both T1DM and T2DM patients showed a significant increase in the abundance of the Lactobacillus genus (p = 0.01) and a decrease in Faecalibacterium (p = 0.02). Additionally, serum levels of IL-6 and TNF-α were significantly elevated in T2DM patients (p = 0.003 and p = 0.005, respectively). Faecal levels of butyrate were significantly reduced in both diabetic groups compared to the controls (p = 0.004).

conclusionBy determining the GM alterations in patients with diabetes, interventional strategies could be designed to modulate the GM composition as an adjunctive therapy in diabetes.
