[Risk factors for the occurrence of bronchiolitis obliterans in children with refractory pneumonia and the predictive value of the factors].

Objectives: To investigate the risk factors for the occurrence of bronchiolitis obliterans (BO) in children with refractory pneumonia (RMPP) and their predictive value of the factors.

Methods: A retrospective analysis was performed for the medical records of 156 children with RMPP who were admitted to the hospital from May 2020 to March 2024. According to the diagnostic criteria for BO, they were divided into a BO group (=76) and a non-BO group (=80).
