Time to ventilation in seconds for extraglottic application and tracheal intubation using the Fastrach™ and the ILTS-D2. Medians, interquartile ranges (IQRs), minima (Min), maxima (Max) and P-values of the particular statistics regarding participant-related censoring: Wilcoxon rank-sum test (attempts without censoring: all extraglottic attempts and intubation attempts 1 and 5), Log-rank test (attempts with censoring: intubation attempts 2, 3 and 4)
