2 Fig 1 (a) Photograph of the C-MAC® laryngoscope. The cable is connected to a display unit. (b) Photograph of the Airtraq® laryngoscope. The TT is preloaded into the chamber of the device. (c) Photograph of the TT in the hockey stick configuration used for tracheal intubation with the C-MAC®.

3 Fig 2 Comparison of IDS score distributions with each laryngoscope. Number of patients is shown above each bar. The IDS scores were lowest with the Airtraq® compared with both Macintosh and C-MAC® laryngoscopes. P<0.001 between groups, Kruskal–Wallis anova on ranks.

4 Fig 3 The Cormack and Lehane scores during the first intubation attempt with each laryngoscope. Number of patients is shown above each bar. The Cormack and Lehane scores were lowest with the Airtraq® compared with both Macintosh and C-MAC® laryngoscopes. P<0.001 between groups, Kruskal–Wallis anova on ranks.

5 Fig 4 Box plot representing POGO scores with each device. The POGO scores were highest with the Airtraq® compared with both Macintosh and C-MAC® laryngoscopes. The middle line represents the median, whereas the borders of the box are the inter-quartile ranges. Outliers are represented by the solid dots. *P<0.05 compared with the Macintosh and C-MAC®, Kruskal–Wallis anova on ranks.

6 Fig 5 Box plot representing VAS difficulty scores with each device. VAS difficulty scores were significantly lower with the Airtraq® compared with both the Macintosh and the C-MAC®. The middle line represents the median, whereas the borders of the box are the inter-quartile ranges. Outliers are represented by the solid dots. *P<0.05 compared with the Macintosh and C-MAC®, Kruskal–Wallis anova on ranks.
