  1. Generalized linear mixed models with random intercept using the logit link function were used to evaluate the association between FAS and cumulative ETI experience.
  2. FAS first attempt success, ETI endotracheal intubation, OR odds ratio, CI confidence interval, VL video laryngoscope, DL direct laryngoscope, BMI body mass index, CA cardiac arrest.
