A
Within each group of the MIF or the breathing frequency, means with the same letter are not significantly different (p-value > 0.05).
B
Calculated using the size-independent (overall) TIL values.
C
P-values were obtained from the two-way ANOVA performed to examine the effect of the MIF on the TIL.
D
P-values were obtained from the two-way ANOVA performed to examine the effect of the breathing frequency on the TIL.
