Correlation between MIP/MEP and spirometry ().

	MIP	value	MEP	value
VC (L)	0.517	0.000	0.344	0.017
FVC (L)	0.509	0.000	0.298	0.040
FEV1 (L)	0.523	0.000	0.307	0.034
FEV1/VC (%)	0.000	0.99	0.001	0.996
PEF (L/min)	0.655	0.000	0.507	0.000

FEV₁: forced expiratory volume in 1 second; FVC: forced vital capacity; MEP: maximal expiratory pressure; MIP: maximal inspiratory pressure; PEF: peak expiratory flow; VC: vital capacity.
