A predictive system for Henoch-Schönlein purpura nephritis established by multivariate analysis plus nomogram model in Chinese hospitalized children: A retrospective cohort study

To the Editor: Renal involvement is recognized as a predominant contributor to the long-term prognosis of Henoch-Schönlein purpura (HSP) and affects 38.5% of patients after a mean follow up of 73.9 months. 1 Baumrin E.
