Lactobacillus regulate muscle fiber type conversion in Chinese native pigs via tryptophan metabolism.

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
Identifying potential gut microbes and metabolites that can influence muscle fiber type is gaining interest in meat quality research. In this study, muscle fiber characteristics, muscle metabolite profiles, and gut microbiota and metabolome were compared among three pig breeds (Taoyuan black, TB; Xiangcun black, XB; and Duroc pigs). The results showed that the slow-twitch fiber percentage was higher (P < 0.05) in native pigs (TB and XB pigs) compared to Duroc pigs. The differences were mainly regulated by Lactobacillus abundance and tryptophan metabolism. Further, fecal microbiota transplantation from XB pigs transferred a higher slow-twitch fiber percentage, Lactobacillus abundance, kynurenic acid level, and AMPK/PGC-1α expression to mice. These findings suggest that Lactobacillus in the colon of TB and XB pigs, through kynurenic acid production, may promote slow-twitch fiber formation via the AMPK/PGC-1α signaling pathway.
