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
Type II ketosis in dairy cows is a common metabolic disorder characterized by hepatic lipid metabolism dysregulation. To investigate hepatic tissue heterogeneity and underlying molecular mechanisms in type II ketosis, this study utilized an integrated multi-omics and functional validation strategy. Serum (n = 20), plasma (n = 6), and liver tissue (n = 1 to 3) samples were obtained from Holstein cows in the early postpartum period (3 to 15 days), comparing ketotic and healthy groups. The experimental design combined plasma metabolomics (3 d postpartum, n = 6), cellular metabolomics (n = 6), single-nucleus RNA sequencing (snRNA-seq; 3 d postpartum, n = 1), bulk RNA-seq of hepatocytes (n = 6), and functional assays performed in primary bovine hepatocytes isolated from healthy donor livers (n = 3). This comprehensive framework enabled a systematic exploration of metabolic dysregulation, cellular diversity, and key disease-associated regulatory pathways. The study identified 15 potential biomarkers and extensive dysregulation of metabolic pathways. Liver tissues comprised 14 distinct cell types, with spatially heterogeneous hepatocyte subpopulations localized in periportal, midlobular, and central venous zones. Central venous hepatocytes were pivotal in lipid metabolism, whose reduction amplified interactions between hepatic stellate and endothelial cells, activating lipid-related pathways and driving disease progression. Critically, the ketone body-butyrate-HADHA axis was identified as a central pathogenic pathway. Silencing HADHA alleviated lipid metabolic dysfunction in hepatocytes induced by exogenous NEFA. Notably, HADHA exhibited dual regulatory roles in hepatic lipid metabolism under distinct pathological contexts. This study bridges hepatic cellular dynamics with systemic metabolic dysregulation, laying a theoretical foundation for mitigating lipid metabolism disorders in dairy cattle and informing translational applications in veterinary medicine.
