Enhancing metabolite coverage using dedicated mobile phases for individual polarity modes in HILIC-MS.
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. Cited by 2 papers.
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 have developed a new hydrophilic interaction liquid chromatography-mass spectrometry (HILIC-MS) method with mobile phases optimized for high metabolite coverage in individual polarity modes. This dual mobile phase strategy expands the range of annotated metabolites and improves identification confidence, providing broader and more accurate metabolic profiles. The incorporation of a bioinert chromatographic system further enhances sensitivity. The bridged ethyl hybrid (BEH) amide column yields the best results for metabolomic analysis among the three chromatographic columns in this comparison. The method development involves investigating the effects of mobile phase composition, pH, and a medronic acid additive on the MS response under bioinert chromatographic conditions. The results highlight the important role of alkaline pH for the sensitive detection of polyphosphorylated metabolites, while demonstrating the redundancy of chelating additives in a fully bioinert system. Finally, the optimized method is applied to mouse plasma, pancreas, and liver samples to demonstrate its versatility and reliable performance in complex biological matrices, establishing it as a powerful tool for confident and reproducible metabolomics studies.
