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

Anti-glomerular basement membrane (anti-GBM) nephritis is a rare but highly aggressive cause of rapidly progressive glomerulonephritis (RPGN). Early recognition is essential, as delayed diagnosis leads to irreversible kidney damage and poor prognosis. We report an 8-year-old girl with anti-GBM nephritis initially misattributed to kidney involvement of IgA vasculitis (IgAV). Diagnosis was confirmed by markedly elevated anti-GBM antibodies and kidney biopsy findings. Despite plasma exchange and immunosuppressive therapy, kidney function deteriorated to kidney failure within several months. This case provides an important clinical insight for pediatric nephrologists: worsening urinary findings or kidney function during follow-up of IgAV should prompt consideration of RPGN and appropriate serological screening, as well as timely kidney biopsy, rather than being attributed solely to IgAV nephritis.
