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
Selenium (Se) is a vital trace element for aquatic organisms. This study investigated the impact of dietary nano-selenium (Nano-Se) on growth, muscle nutritional quality, protein deposition, and selenoprotein gene expression in channel catfish (Ictalurus punctatus). A total of 12,000 catfish (85.74 ± 5.75 g) were randomly allocated into four groups (0, 1.5, 3.5, and 5.0 mg/kg Nano-Se) for 60 days. Optimal Nano-Se supplementation (3.5 mg/kg) significantly improved weight gain rate (WGR), specific growth rate (SGR), and feed conversion ratio (FCR) compared to the control. Additionally, Nano-Se enhanced muscle protein, lipid content, and free amino acid levels while modulating fatty acid composition, indicating improved flesh quality. Histological analysis revealed increased myofiber diameter, suggesting muscle growth promotion. Mechanistically, Nano-Se enhanced protein deposition by activating the PI3K/AKT/TOR pathway, stimulating protein synthesis, while simultaneously inhibiting proteolytic pathways (ubiquitin-proteasome and autophagy-lysosome systems). Furthermore, Nano-Se upregulated 17 key selenoprotein genes (Gpx1a, Gpx2, Gpx3, Gpx9, Selenoh, Selenoi, Selenok, Selenom, Selenop, Selenot1a, Selenot2, Selenow1, Selenow2, Selenoe, Selenoo1, Dio2, and Dio3b), implicating their roles in muscle development and oxidative stress regulation. The above results indicate that adding Nano-Se to feed can improve growth performance, flesh nutritional quality, muscle protein deposition, and selenoprotein genes expression of channel catfish.
