Fig. 5: Incidence of esophageal intubation and reintubation due to malpositioning.

A Forest plot of esophageal intubation events across studies, with pooled incidence shown as a diamond. B Forest plot of reintubation due to malpositioning, with pooled incidence shown as a diamond. Squares represent study-specific estimates, horizontal lines indicate 95% CIs, and diamonds show pooled effects.
