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

Proliferative glomerulonephritis with monoclonal immunoglobulin deposits is a form of monoclonal gammopathy of renal significance that can rarely co-occur with thrombotic microangiopathy (TMA). We report a rare case in a patient who presented with nephrotic syndrome, in whom the renal biopsy showed TMA and underlying granular electron-dense deposits predominantly along the subendothelial aspect of the glomerular basement membrane and mesangium. Immunofluorescence performed on proteinase-digested formalin-fixed, paraffin-embedded sections showed IgG3 kappa light chain restriction. Further clinical, radiologic and haematologic investigations showed no evidence of any underlying neoplastic B-cell or plasma cell clone. Following multidisciplinary team input, the patient was treated with bortezomib and plasma exchange, allowing long-term clinical stabilisation.
