Notes:
a
Mean (SD);
b
median (IQR);
c
mean (SD) using t-test. P-values were calculated using Student’s t-test.
Abbreviations: BMI, body mass index; FEV1, forced expiratory volume in 1 second; FVC, forced vital capacity; MMSE, Mini Mental State Examination; PEFR, peak expiratory flow rate; SVC, slow vital capacity; SD, standard deviation; IQR, interquartile range.
