  1. Spleen salvage was defined as the avoidance of total splenectomy. The number of hospital-free days at day 28 was defined as the number of days that the patient was alive and not hospitalized during the first 28 days after the hospital admission. Hospital-free days at day 28 is expressed as median IQR. The definition of complications is described in Appendix E1. Data are reported as number (%) or relative risk/difference [95% confidence interval].
  2. CNS, central nervous system; IQR, interquartile range; SAE, splenic artery embolization.
