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

Membranoproliferative glomerulonephritis (MPGN) is a histopathological pattern that represents a spectrum of glomerular injury diseases. MPGN is usually associated with infections, autoimmune diseases and monoclonal gammopathies. Monoclonal gammopathy of renal significance (MGRS) is any proliferative B-cell or plasma-cell disease that causes abnormal buildup of monoclonal proteins in the kidneys. It is usually underdiagnosed due to its rarity. We present a case of a 74-year-old woman referred to nephrology with worsening creatinine levels, proteinuria and microscopic hematuria. Laboratory evaluation showed low C3 levels and elevated serum free light chain ratio. Kidney biopsy showed immune deposits consistent with cryoglobulinemic glomerulonephritis secondary to MGRS. Patient was treated with prednisone and mycophenolate mofetil, resulting in improvement in the creatinine functions, proteinuria, and hematuria.
