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

In this study, we developed a cold solvent washing-enhanced AFADESI-MSI spatial lipidomics approach that improves detection sensitivity of tissue lipid metabolites while preserving molecular spatial distribution fidelity. Using brain tissue homogenate sections as benchmark samples, the solvent composition, washing temperature, and washing time were systematically optimized, with the optimal condition determined as methanol/water (8:2, v/v) treatment at -80 °C for 1 h. The optimized method yielded an average of more than 150 enhanced mass spectral peaks in mouse brain, kidney, and liver tissues, with significant signal enhancement. Molecular imaging of fine cerebellar structures (fiber tracts, ~60 μm) confirmed that lipid spatial fidelity was largely maintained. Clinical application to pancreatic cancer tissues revealed that PC and PE species were significantly upregulated in cancer tissues, with longer-chain PC species (e.g., PC 38:5, PC 40:7) showing preferential upregulation. Notably, PC 36:3 exhibited robust discriminatory power between cancer and distal margin tissues, demonstrating the broad tissue applicability of this method in revealing previously undetectable lipid spatial distributions and providing a novel analytical tool for lipid biomarker discovery in pancreatic cancer.
