A unique arsenic profile with unusual arsenic compounds discovered in the edible mushroom Sparassis crispa.

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 edible and medicinal mushroom Sparassis crispa contains a diverse profile of arsenic species. We investigated the arsenic profile of extracts from four different fruiting bodies of S. crispa originating from Austria and Czechia. Besides the previously known arsenic species arsenocholine, trimethylarsine oxide, trimethyl(2-carboxyethyl)arsonium, arsenobetaine amide, and the tetramethylarsonium ion, we were able to identify the uncommon α-glycerophosphorylarsenocholine-previously only identified as a minor arsenic species in marine animals-as a major arsenic species. Furthermore, a novel arsenic compound, i.e., β-methyl arsenocholine, was identified as a naturally occurring compound in all investigated samples of S. crispa. We present methods for the preparation of synthetic α-glycerophosphorylarsenocholine and β-methyl arsenocholine, which were used to confirm their presence in S. crispa.
