Human Health Risk Assessment due to the Incidence of Heavy Metals in Different Commercial Feeds Used for the Culturing of Biofloc Fish (Nile tilapia: Oreochromis niloticus).
Article in Biological trace element research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Fish meat is a major and rich source of white protein; its quality is determined by the fish feed. However, the low-quality feed may contribute to a source of contamination if it does not fulfill the standard protocol. Biofloc is considered one of the most efficient, successful aquacultures, but this system is still under investigation for its efficiency and safety. Thus, current study focused on the heavy metal contamination in biofloc fish fed on different commercial feeds and human health risk analysis. Samples of extensively used three feeds (Supreme™, Hitech™, and MH-Aqua™), tanks water, and biofloc fish (gills, liver muscle) were collected for heavy metals (Cu, Cd, Pb, and Cr) analysis using atomic absorption spectrometry. An experiment was designed by dividing the fish into three groups: group 1 (Supreme™), group 2 (Hitech™), and group 3 (MH-Aqua™). A bioaccumulation factor and human health risk assessment have been calculated to measure fish and human health. Results revealed that most of the heavy metal concentration was higher (P < 0.05) in MH-Aqua™ feed compared to others. Similarly, heavy metal concentration was higher (P < 0.05) in the water of group 3, where fish was cultured on MH-Aqua™ feed. However, in the fish gills, liver, and muscle, the heavy metal concentration was significantly greater in group 3 fed on MH-Aqua™ feed, followed by group 1. Heavy metals in all feeds were positively correlated to the heavy metal concentration of the fish muscles. The bioaccumulation factor for Cu and Pb was higher in the fish liver, Cd and Cr in the case of fish gills, and least in the fish muscle. EDI and THQ values vary in all the groups, while the HI value was found lower than 1 in group 1 and group 2 but higher in group 3 fed on MH-Aqua™ feed. Strict checks and balances in formulating a diet will be helpful to progressively lower the amount of dangerous heavy metals.
