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

objectivesCrescentic IgA nephropathy (C-IgAN) is defined as IgAN with more than 50% of glomeruli showing crescents. C-IgAN in children is rare; we investigate in detail for the first time.

methodsWe retrospectively analyzed the 515 consecutive children who were newly diagnosed with biopsy-proven IgAN between June 1976 and May 2010. We compared clinical and pathological findings between C-IgAN and non-C-IgAN.

resultsAmong 515 cases of childhood IgAN, 25 children (4.9%) had C-IgAN. Of these 25, 16 children (64%) were referred to hospitals by annual school screening. Clinical findings showed significant differences in gross hematuria (76 vs. 50%, p = .03), excretion of proteinuria (1.9 vs. 0.5 g/day/m

conclusionsWe confirmed the importance of school screening to find C-IgAN. Although most crescents (mean: 98.1%) of C-IgAN were cellular/fibrocellular, and acute lesions were well modified with combination therapy, the presence of tubular atrophy in C-IgAN may be the reason for poorer prognosis.
