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

Reliable non-invasive biomarkers for early detection of diabetic nephropathy (DN), a leading cause of chronic kidney disease, remain limited. In this study, we isolate urinary extracellular vesicles (uEVs) using wheat germ agglutinin (WGA)-conjugated magnetic beads and identify cytoskeleton-associated protein 4 (CKAP4) as a potential diagnostic biomarker for DN. Proteomic profiling and flow cytometry show that CKAP4 levels are significantly higher in uEVs from DN patients than in those from diabetic, non-diabetic renal disease (NDRD) and healthy control groups. Receiver operating characteristic (ROC) analysis demonstrates excellent diagnostic performance, with area under the curve (AUC) values of 0.9998 (sensitivity = 98.77%, specificity = 100%) for DN versus controls, and 0.9859 (sensitivity = 95.72%, specificity = 99.24%) for DN versus diabetes mellitus. CKAP4 levels, elevated even at early-stage DN, positively correlate with glomerulosclerosis, increasing with the severity of interstitial fibrosis and tubular atrophy (IFTA). Mechanistically, CKAP4-containing EVs derived from high glucose-treated podocytes promote vascular calcification in vascular smooth muscle cells via YAP signalling. These findings identify CKAP4 in podocyte-derived uEVs as a robust non-invasive biomarker for early DN detection and provide new insights into the vascular pathology associated with the disease.
