1 · What the graph read from 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.

2 · The registry

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

Oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs) are a group of PAHs derivatives formed by chemical or microbial oxidation that can negatively affect benthic organisms. However, their distribution in coastal sediments remains poorly understood. In the present study, we examined the distribution and ecological risks of oxy-PAHs in sediments collected from 18 sites in Tokyo Bay, Japan. Concentrations of target oxy-PAHs ranged from 10.2 to 1299 ng/g dry weight, generally exceeding previously reported values. Strong correlations were found between oxy-PAHs and sediment carbon content and between oxy-PAHs and parent PAHs, possibly showing common sources or transformation pathways. Lethal and developmental effects were observed in Java medaka (Oryzias javanicus) embryos exposed to the artificial sediments spiked with two oxy-PAHs (7,12-benz(a)anthraquinone and 1,4-naphthoquinone) found at several locations in Tokyo Bay. Both risk quotient indices exceeding 1 were shown at more than 10 sites, and suggest that these 2 substances may pose potential threats to benthic organisms at a number of sites in Tokyo Bay.
