Formation of polybrominated dibenzofurans (PBDFs) after heating of a salmon sample spiked with decabromodiphenyl ether (BDE-209).

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
Fish is a major source for the intake of polybrominated diphenyl ethers (PBDEs). However, fish is scarcely consumed without being cooked, and previous studies showed that the heating of salmon fillet contaminated with BDE-209 for longer periods of time was accompanied with the partial transformation of this brominated flame retardant. In this study, we heated salmon fillet spiked with BDE-209 and verified that this process was linked with the formation of polybrominated dibenzofurans (PBDFs) in the fish. Each minute of heating 1 g salmon fillet spiked with 200 ng BDE-209 generated about 0.5 ‰ PBDFs relative to the initial amount of the pre-dioxin BDE-209. This result of the chemical analysis by gas chromatography with mass spectrometry (GC/MS) was verified by means of an effect-directed bio-assay (DR CALUX). While unheated salmon with BDE-209 and heated salmon without BDE-209 were tested nontoxic, the bioanalytical response of fish linearly increased upon heating. We also found that PBDF formation did neither occur with BDE-47 nor when BDE-209 was heated in edible oil instead of salmon fillet. Due to the formation of PBDFs in this process, the consumption of heated, BDE-209 contaminated fish may add to the uptake of dioxin-like compounds with our diet.
