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

Despite widespread storage of frozen whole blood (FWB) in biobanks worldwide, its suitability for extracellular vesicle (EV) research remains largely unassessed. Here, we developed a robust and practical workflow for EV-based cancer biomarker analysis from FWB by comparing differential ultracentrifugation (dUC), size-exclusion chromatography, and their combination. All methods successfully recovered vesicles within the expected 50-150 nm range, enriched for canonical EV markers, while reducing blood-derived EV contaminants, and displayed vesicle-like morphology. Among tested methods, dUC emerged as the most cost-effective and labor-efficient approach. Applying this pipeline to biobanked FWB samples from patients with small intestinal neuroendocrine neoplasms yielded an average of ∼1,000 proteins detected per sample using mass spectrometry-based proteomics, including known neuroendocrine markers and enrichment in synapse organization signaling pathways. These findings demonstrate the feasibility of EV isolation from FWB and biomarker-relevant downstream analysis, highlighting the untapped potential of EV-based biomarker discovery across diseases from existing biobanks.
