  1. All variables listed in the table were used to estimate the propensity score to predict the likelihood of undergoing SAE. Resuscitation management is an important step needed to correct physiological disorders that must be performed in trauma bays. Categorical variables are expressed as absolute counts (%).
  2. SAE, splenic artery embolization; SMD, standardized mean difference.
