From: Mechanical chest compression devices in the helicopter emergency medical service in Switzerland

Variable Multivariate Model (Complete Case Analysis) Multivariate Model (Multiple Imputation)
OR 95% C.I. p-value OR 95% C.I. p-value
Male Sex 0.456 0.167 to 1.248 0.126 0.672 0.338 to 1.336 0.258
CPR by Lay 0.554 0.255 to 1.202 0.135 0.610 0.307 to 1.214 0.111
Shockable Rhythm 0.176 0.084 to 0.372 < 0.001 0.092 0.073 to 0.286 < 0.001
  1. OR Odds ratio, 95% C.I. 95% Confidence interval of the odds ratio
  2. Complete-Case Analysis: Included observations n = 315, 163 missing observations
  3. Multiple-Imputation Model: No of Imputations = 10, No of Iterations = 50, Method = PMM
  4. Female sex, not receiving lay CPR and non-shockable cardiac rhythm served as the reference groups in both models
