Abundance, composition and vertical distribution of polycyclic aromatic hydrocarbons in sediments of the Mai Po Inner Deep Bay of Hong Kong.
Article in Ecotoxicology (London, England), 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
The distribution and changes of polycyclic aromatic hydrocarbons (PAHs) contamination in mangrove sediments of Mai Po Inner Deep Bay Ramsar Site of Hong Kong SAR were investigated. Surface sediments (10 cm) collected from four sampling sites (SZ, SP, MF and M) exhibited significant spatial variations in concentrations of total PAH (with ΣPAHs ranging from 161.7 to 383.7 ng g(-1) dry wt), as well as the composition of 16 US EPA priority PAH compounds. The highest PAHs concentrations were found in the mangrove sediments. Moreover, a sediment core was extracted from mangrove area is used to reconstruct the high-resolution depositional record of PAHs by (210)Pb isotope analysis, showing the amounts of PAHs remained relatively constant for the past 41 years. Urbanization of Shenzhen Economic Zone, the rapid increase in vehicle numbers and energy consumption in the last two decades contributed to the PAHs detected in sediments. The source-diagnostic ratios indicated that pyrogenic input are important throughout the record and the surface sediments, and suggest that diesel fuel combustion, and hence traffic of heavier vehicles, is the most probable cause of PAHs.
