Circulating bile acid profiles characteristics and the potential predictive role in clear cell renal cell carcinoma progression.

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
backgroundThe incidence of clear cell renal cell carcinoma (ccRCC) has steadily increased over the past decade, and recent studies have linked bile acid (BA) metabolism to its development. However, the metabolic profile of BAs and their potential as biomarkers in ccRCC pathogenesis remain poorly characterized, making their evaluation crucial for advancing disease understanding and management.
methodsA total of 68 newly diagnosed ccRCC patients and 63 healthy controls were enrolled. Serum bile acid (BA) profiles were measured using Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry (UPLC-MS/MS). The Orthogonal Projections to Latent Structures Discriminant Analysis (OPLS-DA) model analyzed differences in serum BA profiles between ccRCC patients and controls. Additionally, the relationship between BA profiles and tumor heterogeneity parameters was investigated. Receiver Operating Characteristic (ROC) analysis identified potential biomarkers for ccRCC pathogenesis.
resultsThe BA profile was altered in ccRCC patients and was not influenced by sex or age. Specifically, primary and secondary unconjugated BA fractions were significantly higher in the ccRCC population. Five BA metabolite candidates exhibited the most significant differences between ccRCC patients and controls. Deoxycholic acid (DCA) was associated with pathological pTNM stage classification and grade. Chenodeoxycholic acid (CDCA) and lithocholic acid (LCA), combined with testosterone, showed potential as biomarkers for the pathogenesis of ccRCC.
conclusionAlterations in the serum BA profile are observed in ccRCC. Deoxycholic acid (DCA) correlates with pathological pTNM stage classification and tumor grade. Additionally, CDCA combined with LCA show potential as biomarkers for ccRCC pathogenesis. CLINICAL TRIAL NUMBER: Not applicable.
