Continuous variables are given as median (interquartile range). The intubation time from first intubation attempt only is used for analysis. P-value was calculated by Friedman test and P<0.05 is considered significant.
DT, device insertion time; TT, tube insertion time; FVT, first ventilation time; MCL, Macintosh laryngoscope.
a)
Calculated by Wilcoxon rank-sum test with Bonferroni correction in post hoc analysis. P<0.0083 is considered significant.
