The primary endpoint was ‘time to successful ventilation’ trial 4. Time points: consecutive trials 1, 2, 3, and 4; the median of the ‘time to successful ventilation’ and ‘time to visualisation’ for each technique: MB Macintosh blade, Bonfils Bonfils intubation fibrescope, CI confidence interval, and n (censored): the number of unsuccessful attempts and those taking longer than 90 s; p: Wald p value from the stratified Cox model testing for the difference between the techniques in each trial [missing data (n = 1)] for participant under the MB in all trials
