Integrated microbiota and metabolomic analysis demonstrates the growth-promoting effects of Lactobacillus plantarum in Nile tilapia (Oreochromis nilotica).
Article in Animal microbiome, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Lactobacillus plantarum, a well-characterized probiotic from terrestrial animals, shows promising effects on fish growth and lipid metabolism. However, its role in promoting protein deposition in fish remains unclear. In this study, 180 juvenile Nile tilapia were randomly assigned to two groups and fed for eight weeks with either a control diet (CK) or a diet supplemented with L. plantarum (LR). The results showed that L. plantarum significantly improved final body weight, weight gain rate, body length, carcass rate, intestinal index, whole-body protein content, and villus length (P < 0.05), accompanied by increased expression of growth-related genes and activation of the mechanistic target of rapamycin (mTOR) pathway. Conversely, the hepatosomatic index, condition factor, mesenteric fat index, hepatic lipid droplets, liver and serum triglycerides were significantly reduced (P < 0.05). The L. plantarum group exhibited downregulated expression of lipogenic genes and upregulation of genes involved in lipolysis, β-oxidation, and fatty acid transport (P < 0.05). Gut microbiota analysis revealed higher α-diversity and increased relative abundances of Pseudomonas and Diaphorobacter, while Cetobacterium, Aestuariivirga, and Aurantimicrobium at the genus level were reduced (P < 0.05). Metabolomic profiling showed elevated bile acids, uridine, phosphatidylcholine, and carnitine derivatives (P < 0.05). To confirm strain-specific effects, germ-free zebrafish were mono-colonized with L. plantarum, leading to suppressed lipogenesis and enhanced lipolysis and growth-related gene expression. Overall, L. plantarum promoted growth while simultaneously reducing fat accumulation, indicating a non-adipogenic growth-promoting effects in Nile tilapia.
