Prediction of 3‐month treatment outcome of IgG4‐DS based on BP artificial neural network

Objective The study aimed to establish an effective back‐Propagation artificial neural network (BP‐ANN) model for automatic prediction of 3‐month treatment outcome of IgG4‐DS. Methods A total of 26 IgG4‐DS patients at Shanghai Ninth People's Hospital from January 2018 to December 2019 were involved in the study. They were all followed for >3 months. The primary outcome was reduction of serum IgG4 (sIgG4) after 3‐month treatment. The...
