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

Nine Japanese children with severe proteinuric Henoch-Schönlein purpura nephritis (HSPN) received prompt initiation of oral prednisolone (1.5 mg/kg/day) combined with an 8-week course of cyclophosphamide (2 mg/kg/day) therapy. All underwent renal biopsy before and after treatment. At presentation, urine protein excretion and histologic indices of the mean activity index, the mean chronicity index and the tubulointerstitial (TI) scores in the patients were 5.0+/-1.4, 4.7+/-1.0, 3.9+/-1.6 and 3.7+/-0.5 g/day, respectively. Urine protein excretion, the activity index and the TI scores decreased significantly at the second renal biopsies obtained at a mean interval of 23 months after the first [0.3+/-0.3, 2.4+/-0.5 and 1.4+/-0.7 g/day ( P<0.01), respectively], while the chronicity index did not change. At the latest observation (mean interval 78 months), all except two showed negative proteinuria while no patient showed renal impairment. Although this case series is without controls, our experience suggests that early treatment with oral prednisolone and cyclophosphamide may be beneficial to a proportion of patients with severe proteinuric HSPN.
