Investigation of matrix effects by crops and their compensation methods in a multiresidue analysis using LC-MS/MS.
Article in Journal of pesticide science, 2025. 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
This study evaluated the matrix effect (ME) in a multiresidue analysis with the modified official Japanese method for agricultural products using liquid chromatography-tandem mass spectrometry (LC-MS/MS). In ME comparisons between the vegetable and fruit samples, it was found that more numerous analytes exhibited ion suppression in the vegetable samples than in the fruit samples, and substantial ion enhancement was not observed in most of the analyte-sample combinations. The ME could significantly vary, even within the same commodity, and it was suggested that sampling has greater influence than measurement when there is a wide ME variability. Dilution, the internal standard calibration method and the matrix-matched calibration method are practical countermeasures against MEs, but certain limitations in their applications should be considered. Moreover, a novel cleanup procedure suitable for hydrophilic neonicotinoid pesticides that minimized the usage of expensive internal standard solutions was suggested.
