CLR: Cuff-Leak Ratio. □: In the inter-group comparison: Level of significance for comparing each group in the follow-up. In the intra-group comparison, three comparisons have been made as follows: *Level of significance for comparing I group vs I + B group, **Level of significance for comparing I group vs I + V group, ***Level of significance for comparing I + B group vs I + V group
