Human exposure risk to semivolatile organic compounds via soil in automobile workshops in Awka, South Eastern, Nigeria.

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
Evaluation of the human exposure risk to semivolatile organic compound (SVOC) levels in soil from automobile workshops in Awka was investigated. Soil samples were collected in both dry and rainy seasons. Solvent extraction of the soil samples was carried out using n-hexane: acetone mixture (1:1). Concentrations of SVOCs were determined using gas chromatography-mass spectrometry. There were higher concentrations of SVOCs in the dry season than in the rainy season. The concentrations of the SVOCs were compared with standards for industrial soils. Concentrations of pentachlorophenol in the samples for dry and rainy seasons were below the Canadian Council of Ministers of Environment (CCME) acceptable limit of 7.6 mg/kg. Eighty percent of soil samples for the dry season and all the soil samples for the rainy season had benzo(a)pyrene concentrations lower than the CCME acceptable limit of 0.7 mg/kg. However, incremental lifetime cancer risk (ILCR
