Integrated chemometric evaluation of morphological traits, chemical composition, and hepatotoxicity of
Article in Frontiers in pharmacology, 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
Ethnopharmacological relevance: The toxicity of Aim: This study aims to establish a new evaluation model that integrates multiparameter chemometric analysis with combined statistical approaches to assess and monitor the toxicity of PM. The multi-index framework included crude drug morphological traits, main chemical constituents (anthraquinones, stilbene glycosides, flavonoids and phenols), and hepatotoxicity across different PM batches. Materials and methods: An ultra-performance liquid chromatography-electrospray ionization-triple-quadrupole tandem mass spectrometry (UPLC-ESI-QqQ-MS/MS) method was first developed to quantify 26 compounds in 61 batches of commercial PM samples. Chemometric analyses, including principal component analysis (PCA) and hierarchical cluster analysis (HCA), were then applied to classify the samples into four groups based on chemical composition. Hepatotoxicity comparisons among these groups were conducted using the Cell Counting Kit-8 assay in HepaRG cells. Subsequently, toxicity-related morphological traits were investigated by quantifying chromaticity values of crude drugs from groups with distinct toxicity profiles. Two key between-group toxicity variables were identified through chemometric analyses, including orthogonal partial least squares discriminant analysis (OPLS-DA) and Results: The established chemical profiling library of PM demonstrated a strong correlation with hepatocytotoxicity. White decoction pieces of PM were found to be safer, while THSG and EG were identified as potential hepatotoxic constituents. Moreover, THSG enhanced the hepatotoxicity of EG, indicating a synergistic effect. Conclusion: The proposed model offers a novel framework linking morphological traits, chemical composition, and hepatotoxicity of PM, offering a reference for the safety evaluation of other medicinal herbs.
