Heavy metal concentrations in four fish species from the Lagos lagoon and their human health implications.
Article in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
Background: Lagos lagoon is constantly being polluted from industrial and human activities. Fishes from Lagos lagoon contribute significant percentages of fish consumption in the Lagos metropolises. Therefore, this study evaluated heavy metal concentrations in tissues of four fish species ( Results: Concentration of the heavy metals in the fish tissues was below the maximum permissible limit in fish. Similarly, the. EDI of the heavy metals in all the tissues was below the recommended allowance whereas, the. THQ estimated for the heavy metals in the tissues of the fish were less than 1. Consumption of arsenic, nickel, and cadmium in the fish might however pose carcinogenic risk. Conclusions: Although, the measured heavy metal concentration were within permissible limits for human consumption, the calculated health risk values indicated that Arsenic, cadmium and nickel might pose significant health risks to consumers. Therefore, biomonitoring of heavy metal accumulation in tissues of fishes must be put into consideration by regulatory authority.
