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 present research examined the use of a commercial acidifier blend (CAB) as a feed supplement on growth, digestive enzymes, antioxidant, immunological biomarkers, and defense of Nile tilapia (Oreochromis niloticus) against Aeromonas sobria disease. Fish (22.7 ± 0.76 g) were fed on 0.0 (the control), 1.0, 2.0, 4.0, or 8.0 g CAB/kg feed for 60 days. After that, fish were intraperitoneally injected with A. sobria, and their survival was monitored for a further 10 days. The fish group that received 4.0 g CAB/kg feed showed the highest growth rate. The improved growth in this group is correlated with the upregulation of mRNA expressions of growth-related genes (IGF-1 and GH). In addition, the highest activities of intestinal proteases, lipase, and α-amylase were observed in fish fed with 4.0 g CAB/kg feed. Compared to the control group, fish fed on CAB-containing diets showed significantly higher activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx). In a parallel way, the mRNA expression of SOD, CAT, and GPx genes were upregulated in CAB-fed groups, particularly at levels of 4.0-8.0 g CAB/kg feed. Conversely, malondialdehyde levels were maximized in the control group but were reduced in CAB-fed fish. Additionally, dietary CAB, especially at levels of 4-8 g/kg diet progressively enhanced the immune function and upregulated the expression of IL-1ß, IL-8, and IL-10 genes. The bactericidal and challenge tests against A. sobria evoked that CAB exhibited antibacterial properties; the maximum mortality rate following the bacterial infection was noted in the control group (90%); meanwhile, CAB-fed fish, especially at a rate of 4.0-8.0 g/kg feed exhibited lower mortality rates (40% and 45%, respectively). Overall, this study recommends incorporating 4.0 g CAB/kg feed to mitigate the negative impacts of dietary soybean and improve the growth, antioxidant, and immunological indices in Nile tilapia fingerlings.
