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

Autoantibody-mediated inflammation drives tissue injury in autoimmune diseases, yet how pathogenic antibodies evoke local immune activation remains poorly understood. Here, we show that spatially organized neutrophil-epithelial niches contribute to kidney injury in myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody-associated glomerulonephritis. Single-cell-resolved spatial transcriptomics of treatment-naïve patient kidney biopsies identified early-phase inflammatory niches enriched with HAVCR1+ injured proximal tubular epithelial cells, neutrophils, lymphocytes, and TREM2+ macrophages. Injured epithelial cells expressed chemokines including CXCL6 and CXCL16, defining a microenvironment associated with local immune cell accumulation. Neutrophils within these niches were characterized by transcriptional programs enriched for type II interferon and Fcγ receptor (FcγR)-related signaling. Mechanistically, combinations of monoclonal anti-MPO antibodies recognizing distinct epitopes enhanced neutrophil activation and induced pauci-immune crescentic glomerulonephritis in mice, recapitulating key aspects of epithelial injury observed in human kidneys. One-armed anti-MPO antibodies engineered to minimize FcγR engagement ameliorated kidney injury in mice. Together, these findings identify pathogenic neutrophil-epithelial niche formation as a driver of autoimmune kidney injury.
