Predicting bacterial infection risk in patients with ANCA-associated vasculitis in southwest China: development of a new nomogram.

Objectives: The aim of this study was to develop and assess a risk nomogram of bacterial infection in patients with ANCA-associated vasculitis (AAV) in southwest China.

Method: We established a prediction model based on a training dataset of 249 AAV patients. The least absolute shrinkage and selection operator (Lasso) was used to screen feature variables.
