  1. The simulation study built on real non-missing data from National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) 2018 was conducted to identify the appropriate MI model for handling missing data
  2. Abbreviations: NH non-Hispanic, CCA complete case analysis, JM joint modeling, MI multiple imputation, FCS fully conditional specification, EDs Emergency Departments
  3. a Non-missing data was used as standard control data
  4. b Excludes sexual assault cases
  5. c Absolute deviation was calculated by using the standard control rate as the reference
