Recent advances in the bioanalysis of acylcarnitines: Methodologies, challenges, and clinical perspectives.
Review in Pharmaceutical science advances, 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
Acylcarnitines (ACs) are a diverse class of fatty acid esters of L-carnitine that serve as critical mediators in energy homeostasis and mitochondrial function. Beyond their classical role in newborn screening for inborn errors of metabolism, ACs have emerged as promising biomarkers for complex pathologies, including cardiovascular diseases, diabetes, and drug-induced toxicities. However, the accurate quantification and comprehensive profiling of ACs in biological matrices remain analytically challenging due to their broad polarity range, vast concentration disparities, and the presence of isomers. This review provides a comprehensive overview of the current bioanalytical strategies for ACs, covering sample preparation techniques and detection platforms, with a focus on liquid chromatography-mass spectrometry. Special attention is given to the differentiation of isomers. Finally, we discuss the clinical applications of ACs profiling and highlight future perspectives, including the integration of ion mobility spectrometry, automated high-throughput workflows, spatial and single-cell metabolomics, and AI-driven analytics, to pave the way for precision medicine.
