Figure 1. Cumulative Incidence of Successful Intubation on the First Attempt.

Figure 1.

Shown are the cumulative incidence and 95% confidence intervals (shaded areas) for successful intubation on the first attempt among patients in each trial group relative to the time since the initial insertion of a laryngoscope blade into the mouth. Successful intubation on the first attempt occurred in 600 of 705 patients in the video-laryngoscope group and in 504 of 712 patients in the direct-laryngoscope group (absolute risk difference, 14.3 percentage points; 95% CI, 9.9 to 18.7; P<0.001 by the chi-square test).
