Notes:
a
Continuous variables (with Gaussian distribution) are indicated by their mean and standard deviations.
b
Continuous variables (with non-Gaussian distribution) are indicated by their median (interquartile range).
c
P-value was computed using t-test for equality of mean values for continuous variables with non-Gaussian distribution and Mann–Whitney U test for continuous variables with non-Gaussian distribution.
Abbreviations: BMI, body mass index; ESR, erythrocyte sedimentation rate; FEV1, forced expiratory volume in the first second; FVC, forced vital capacity; IKE, isometric knee extension; MoCA, Montreal Cognitive Assessment; 6MWD, 6-minute walking distance.
