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

backgroundCorticosteroids have been shown not to prevent the development of Henoch-Schönlein nephritis. However, long-term follow-up data are scarce.

methodsThe long-term outcome of patients in a randomized placebo-controlled prednisone study was evaluated 8 years later with a health questionnaire completed by 160/171 (94%) patients and by urine and blood pressure screening (138/171, 81%).

resultsTwelve patients had hematuria and/or proteinuria and seven had hypertension. The patients with nephritis at onset of Henoch-Schönlein purpura (HSP) had an increased risk of hypertension and/or urine abnormalities (odds ratio 3.6, p = 0.022, 95% confidence interval 1.3-10.0). There were no differences between the prednisone and placebo groups. Recurrences of purpura were reported by 15 patients, with some recurrences continuing for 10 years. All five reported pregnancies were complicated by proteinuria. Four patients presented with hematuria and/or proteinuria at the control visit, and four had hypertension. Of these, two had a decreased estimated glomerular filtration rate.

conclusionsHSP has a good long-term prognosis in unselected patients, although skin relapses with/without late-onset nephritis may occur, even a decade after the initial disease. Urine and blood pressure abnormalities 8 years after HSP are associated with nephritis at its onset. Early prednisone treatment does not affect the outcome and should not be routinely used.
