Table 4 Analyses of gasping during transportation by EMS effect on favourable neurological outcome

From: Gasping during refractory out-of-hospital cardiac arrest is a prognostic marker for favourable neurological outcome following extracorporeal cardiopulmonary resuscitation: a retrospective study

Analysis method Odds ratio 95% CI P value
Unadjusted 8.37 3.64–19.27 < .001
Adjusted using logistic regression 9.52 5.31–17.08 < .001
IPTW using PS 9.14 3.36–24.85 < .001
  1. The IPTW method creates a synthetic sample in which the distribution of measured baseline covariates is independent of exposure assignment. The weight of each participant is calculated using two variables: the participant’s exposure status (0 for absence of gasping and 1 for presence of gasping) and the PS of the participant. The weight of the participant is equal to the inverse of the probability of receiving the treatment that the participant actually received
