Characterizing the Elemental Metabolome in Asparagus officinalis with Multielemental Speciation Analysis.
Article in Journal of agricultural and food chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We report a multielemental and quantitative speciation analysis study with chromatographic inductively coupled plasma-mass spectrometry (ICP-MS/MS) detection involving four elements (sulfur, selenium, arsenic, and phosphorus) in Asparagus officinalis. The samples were locally purchased and labeled to originate from different regions in two continents. Major compounds were identified and quantified with confirmation based on chemical synthesis in pure form. Nontargeted analysis revealed significant quantitative and qualitative variation for the elemental metabolomes among samples, particularly sulfur and arsenic. Sharp contrast was observed in the diversity of the profiles between sulfur and selenium, providing insight into metabolism selectivity in Asparagus. Inorganic and methylated arsenic were both detected, but their ratios showed wide variation between samples. The present work shows the potential of multielemental speciation analysis with ICP-MS/MS as a novel dimension for food characterization based on studying heteroatom-tagged metabolome.
