Health risk assessment of PAHs and heavy metal levels in periwinkles (Pachymelania fusca mutans) and crabs (Scylla serrata) consumed in crude oil-contaminated coastal regions of Southern Nigeria.
Article in Toxicology reports, 2025. 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
This study was conducted to evaluate the health risks related to eating crabs and periwinkles from Southern Nigerian coastal areas that are contaminated by crude oil. Periwinkles and crabs from contaminated locations were tested for Polycyclic aromatic hydrocarbon (PAH) and heavy metal (HM) levels using US-EPA standard, and the health risks to humans of eating these seafood were assessed. 20 samples of periwinkles and crabs were collected from crude oil-polluted coastal areas. Health risk assessments were conducted using Dietary Daily Intake (DDI), PAH4 index, Carcinogenic Toxic Equivalent (TEQs), Excess Cancer Risk (ECR) for PAHs, as well as Hazard Quotient (HQ) and Cancer Risk Assessment (CRA) for HMs. The PAH concentration in periwinkles and crabs are 0.76 mg/kg and 0.49 mg/kg respectively. Dietary daily intake (DDI) of individual PAHs for Periwinkle ranged from 0 to 0.0126 and for crabs, it ranged from 0 to x10
