A network plot of direct comparisons for all included randomized controlled trials for the outcome of unassisted tracheal intubation. The width of the lines is proportional to the number of trials comparing each pair of treatments, and the size of every node is proportional to the number of randomized participants (sample size). A. The overall success rate of unassisted tracheal intubation by ITT; B. The overall success rate of unassisted tracheal intubation by PP; C. The success rate at first attempt by ITT; D. The success rate at first attempt by PP. ITT, intention to treat; PP, per protocol. SFT = single-use LMA-Fastrach; PLA = CobraPLA; Air = Air-Q; FTR = LMA-Fastrach; gel = i-gel; Aur = Ambu-Aura; CTR = LMA-CTrach.

The SUCRA values of different supraglottic airway devices as a strategy for tracheal intubation. A. The overall success rate of unassisted tracheal intubation by ITT; B. The overall success rate of unassisted tracheal intubation by PP; C. The success rate at first attempt by ITT; D. The success rate at first attempt by PP. SUCRA, surface under the cumulative ranking curve; ITT, intention to treat; PP, per protocol. SFT = single-use LMA-Fastrach; PLA = CobraPLA; Air = Air-Q; FTR = LMA-Fastrach; gel = i-gel; Aur = Ambu-Aura; CTR = LMA-CTrach.
