Table 1 “Time to ventilation” in seconds using the supraglottic devices

From: The novel intubating laryngeal tube (iLTS-D) is comparable to the intubating laryngeal mask (Fastrach) – a prospective randomised manikin study

  1. Time points: consecutive trials 1, 2, 3, 4; median, minimum, maximum, upper and lower quartile of ‘time to ventilation’ for the particular instrument displayed as table and boxplot; after trials 1, 2 and 3, the Fastrach could be inserted 1 s faster than the iLTS-D in trial 4 (primary endpoint: Fastrach: median: 13.5 s., iLTS-D: 14.5 s., p = 0.04). Though statistically significant, 1 s is not considered to be a relevant amount of time
