Respiratory parameters and wet/dry weight ratio.

	Pig groups		Rat groups
	P-NtV	P-HtV	Rat-NtV	Rat-HtV
Tidal volume (mL)^a, b	270.0±31.6	1583.3±51.6	3.7±0.3	15.8±1.7
Plateau airway pressures (cm H2O)^a, b	13.5±1.7	57.3±8.2	12.0±1.1	38.3±4.3
Wet/dry ratio^a, b	4.33±0.99	5.60±0.37	4.43±0.10	4.10±0.07

Values are mean ± SD. P-NtV: pigs with normal tidal volume; P-HtV: pigs with high tidal volume; Rat-NtV: rats with normal tidal volume; Rat-HtV: rats with high tidal volume.
^a𝑃<0.01 between P-HtV and P-NtV groups.
^b𝑃<0.01 between Rat-HtV and Rat-NtV groups.
