In the Summary of this paper [1], the sentence:

In this scenario, the median (interquartile range [range]) duration of tracheal intubation was significantly longer with the InnoScope (53 (20–100 [15–120]) s) compared with the Macintosh laryngoscope (27 (20–62 [15–120]) s), p = 0.01.

should have read:

In this scenario, the median (interquartile range [range]) duration for tracheal intubation was significantly longer with InnoScope compared with the Macintosh laryngoscope, 70 [19-120 (15-120)] s vs 30 [21–58 (15–120)] s, p = 0.01.
