Correlation analysis of spirometry data with constant a

Variable vs. constant a	All (n = 17)	Men (n = 8)	Women (n = 9)
FVC	−0.54^*	NS	NS
FEV_1.0	−0.59^*	NS	−0.69^*
FEV_1.0/FVC	−0.49^*	NS	−0.62
PEF	−0.68^*	NS	−0.76^*

Definitions of abbreviations: FVC, forced vital capacity; FEV_1.0, forced expiratory volume in 1 s; FEV_1.0/FVC, forced expiratory volume in 1 s/forced vital capacity; PEF, peak expiratory flow. NS, non-significant correlation (P > 0.05).

Statistically significant correlation (P < 0.05).
