Construction of SAE prediction nomogram in the training cohort. The points of all features were added to obtain the total points, and a vertical line was drawn on the total point to obtain the corresponding ‘predicted value’, which indicates the risk of SAE. PaCO2: arterial partial pressure of carbon dioxide; PCIS: pediatric critical illness score; RR: respiratory rate; BUN: blood urea nitrogen; APTT: activated partial thromboplastin time.
