Study design. This research began with records of all patients whose blood-culture samples were obtained between July 2012 and September 2020. All participants were separated into training and testing cohort. And a new validation cohort were obtained between October 2020 and December 2021. A prognostic model was constructed using a training cohort estimated in testing and new validation cohorts. Finally, an online nomogram was generated based on the prognostic model.
