Changes in fluid leakage volume over time at each intra-cuff pressure. Data points are medians. Error bars represent interquartile ranges. Group 25: Intra-cuff pressure of 25 cm H2O (●); group 50: Intra-cuff pressure of 50 cm H2O (○); group 100: Intra-cuff pressure of 100 cm H2O (▼). * P < 0.008 among all three groups. † Corrected P < 0.020, group 100 vs. group 25 and group 100 vs. Group 50.
