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

A 47-year-old man with nephrotic syndrome and stage 4 chronic kidney disease was diagnosed with C1q nephropathy presenting with focal segmental glomerulosclerosis (FSGS) on a renal biopsy. A genetic analysis performed because of a family history of microscopic hematuria and lamellar glomerular basement membranes identified a heterozygous COL4A4 variant, leading to a genetic diagnosis of autosomal-dominant Alport syndrome (ADAS). Despite immunosuppressive therapy, the patient progressed to end-stage kidney disease much earlier than in previously reported cases of C1q nephropathy. This case suggests that the synergistic effects of C1q nephropathy-induced podocyte damage and abnormal glomerular basement membrane due to ADAS may promote rapid progression of FSGS.
