Simple, Sensitive and Simultaneous Determination of Free D3 and K2 Vitamins in Fortified Chicken Meat Products by LC-MS/MS with Electrospray Ionisation.
Article in Foods (Basel, Switzerland), 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 rapid and simplified LC-MS method was developed for quantifying vitamins D3 (cholecalciferol) and K2 (menaquinone-4 and menaquinone-7) in high-fat chicken meat products. Sample preparation involves a two-step solvent extraction followed by centrifugation. Efficient separation was achieved on a Gemini C18 column, and electrospray in positive mode was used for detection. Method validation confirmed good performance and reproducibility. The method was successfully applied to both fortified and unfortified chicken pâté samples. Owing to its simplicity, robustness, and sensitivity, this approach provides a practical and reliable means for quantifying fat-soluble vitamins in complex animal-derived matrices and can serve as a foundation for broader applications in high-fat food products.
