Statistical results of main indexes of lung function examination

Index	FVC/L	FVC%	FEV1/L	FEV1%	TLC/L	TLC%
BMI, body mass index; FVC, forced vital capacity; FVC%, percentage of estimated FVC; FEV1, forced expiratory volume in one second; FEV1%, percentage of estimated FEV1; TLC, total lung capacity; TLC% percentage of estimated TLC. Data are shown as x±s. *P < 0.001, vs. Male; # P < 0.05, vs. BMI 18-24 kg/m2; △P < 0.05, vs. Time from injury < 1 years.
