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

backgroundInulin is widely recognized for its ability to improve glucolipid metabolism and modulate the gut microbiome and metabolome. However, the potential to influence pork flavor development through gut environment changes in animal husbandry remains unexplored. This study investigated the relationships among systemic health, meat flavor, gut microbiome, and metabolome in pigs fed a diet supplemented with inulin. Thirty-six male Duroc × Landrace × Yorkshire pigs (75.0 ± 1.5 kg) were divided into 2 groups, and fed either a regular diet (CON group) or a diet containing 0.5% inulin (INU group) for 60 d.

resultsInulin supplementation did not adversely affect production or slaughter performance (P > 0.05) but enhanced systemic health by improving serum biochemistry indicators (P < 0.05). Descriptive analysis of pork composition revealed numerically higher levels of key fatty acids (C16:0, C18:0, C18:1) and umami-related amino acids (e.g., glutamic acid) in the INU group compared to the CON group. Inulin supplementation also modulated the gut microbiome, reducing alpha-diversity and increase specific microbes including Lactobacillus, Lachnospiraceae_NK4A136_group, Romboutsia, Family_Xlll_AD3011_group, Roseburia, and Turicibacter. Furthermore, inulin supplementation significantly altered metabolic pathways, down-regulating arginine biosynthesis, linoleic acid metabolism, riboflavin metabolism, and alanine, aspartate, and glutamate metabolism. These microbial and metabolic changes strongly correlated with the observed alterations in pork quality.

conclusionDietary inulin supplementation represents a promising strategy to modulate pork quality and systemic health without compromising productive performance. However, due to the exploratory nature of the amino acid and fatty acid analyses with limited sample size, further studies are needed to further confirm these findings.
