Development of a corn flour certified reference material for the accurate determination of aflatoxins.
Article in Analytical and bioanalytical 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
A corn flour certified reference material (CRM), KRISS CRM 108-01-013, was developed to support accurate measurement of aflatoxins (AFs). Corn flour naturally contaminated with AFs was mixed with AF-free corn flour to obtain a material with representative contamination levels. The mixed material was freeze-dried, milled, sieved, and thoroughly homogenized, and then dispensed into units containing approximately 15 g and stored at - 70 °C. Characterization was carried out using a validated isotope-dilution ultra-high-performance liquid chromatography-tandem mass spectrometry reference measurement procedure. Low between-bottle variability was observed, with relative standard deviations of 1.6 %, 1.0 %, 0.8 %, and 0.9 % for aflatoxin B
