  1. *p < 0.01 for comparison with the younger group;
  2. r is the correlation coefficient between the parameters and age; all correlation coefficients listed are significant at the 0.01 level. Spearman correlation coefficient was used to analyse MVV (with non-normal distribution), and Pearson’s correlation coefficients were used to analyse the normally distributed variables
