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
To promote fish's immunity against pathogens in the aquaculture industry, fish dietary fortification with additives or compounds has increasingly attracted attention. In the present study, zebrafish (Danio rerio) was used as an animal model to investigate the effects of purslane, Portulaca oleracea, extract (PE) on the relative expression level of some immune-related genes. A total of 300 zebrafish were randomly divided into four treatment groups and fed for 8 weeks with the basal diets supplemented with 0.5, 1, 1.5, and 2% of PE. The control group was fed with a basal diet without PE. At the end of 8 weeks, the mRNA expression levels of interleukin 1-beta (IL-1β), interleukin 10 (IL-10), transforming growth factor-beta (TGF-β), tumor necrosis factor-alpha (TNF-α), superoxide dismutase (SOD), and lysozyme (LYZ) in the fish were evaluated. The results showed that the mRNA expression level of IL-1β was significantly upregulated in the fish fed with 1 and 2% PE compared to the control group (p < 0.05). Moreover, the evaluation of the mRNA expression level of TGF-β was significantly increased in a dose-dependent manner in the 1.5 and 2% fed groups compared to the control group (p < 0.05). However, the IL-10 was significantly downregulated in all treated groups compared to the control group (p < 0.05). The expression of the TNF-α gene was not affected amongst all groups by the inclusion of PE in the zebrafish diet (p > 0.05). Based on the results, the diet supplemented with 1.5 and 2% PE significantly upregulated the mRNA expression levels of LYZ and SOD, respectively, compared to the control group (p < 0.05). In conclusion, dietary inclusion of PE may result in beneficial effects on some immune responses via upregulation of some immune genes in zebrafish.
