This study collected clinical, laboratory, and CT parameters of acute patients with acute PE from admission. The outcomes of interest were defined as the occurrence of adverse outcomes within 30 days after admission into hospital.~Eligible patients were randomized in some ratio into derivation and validation cohorts. The derivation cohort was used to develop and evaluate a multivariable logistic regression model for predicting the outcomes of interest. The discriminatory power was evaluated by comparing the nomogram to the established risk stratification systems. The consistency of the nomogram was evaluated using the validation cohort.
