Fig. 2

Comparison of maximum applied forces on maxillary incisors by each laryngoscope and airway adjunct. Column scatter plots representing the data distribution (circles), mean (horizontal bar), and standard deviation (vertical bar). The P values were derived from two-way analysis of variance. n = 209 in each group. DL: direct laryngoscope; ETI: endotracheal intubation; GEB: gum-elastic bougie; VL: video laryngoscope
