Fig. 2 Forest plot of the sucess rate of tracheal intubation using the videolaryngoscopes compared with the Macintosh laryngoscope. The centre of each square represents the relative risk for individual trials, and the corresponding horizontal line represents the 95% CI. The diamonds represent the pooled results.

Fig. 3 Forest plot of intubation time for tracheal intubation using the videolaryngoscopes compared with the Macintosh laryngoscope. The centre of each square represents the weighted mean difference for individual trials, and the corresponding horizontal line represents the 95% CI. The diamonds represent the pooled results.
