1 · What the graph read from it

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.

2 · The registry

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

Hepatocellular carcinoma (HCC) remains a leading cause of cancer mortality, and current biomarkers such as alpha-fetoprotein (AFP) lack diagnostic accuracy. Here, we report the first comprehensive profiling of the plasma endogenous phosphopeptidome in HCC, cirrhosis, and healthy controls using a digestion-free LC-MS/MS workflow. From 60 plasma samples, 1,365 phosphopeptides corresponding to 549 proteins were identified and quantified. Among these, the statherin-derived peptide DSSEEKFLR demonstrated outstanding discrimination between HCC and cirrhosis (AUC = 0.968), outperforming AFP (AUC = 0.648). Additional peptides, including PPGAPHTEEEGAE (NST1), YEYDELPAKDD (C4A), SLPGESEEMMEEVD (ITIH4), and VSLGSPSGEVSHPRKT (AHSG), also showed high accuracy (AUC > 0.80). Functional enrichment revealed perturbations in acute-phase response, coagulation, lipid metabolism, and LXR/RXR signaling. Collectively, this work defines a novel plasma phosphopeptide signature that reflects disease-specific proteolytic and phosphorylation dynamics, providing a foundation for developing biomarkers for early detection and clinical monitoring of HCC.
