highly significantp < 0.001
The mean difference between groups was highly significant for height (5.62, p < 0.001), 6MWT (3.46, p = 0.004), height/foot length ratio (H/FL) (3.43, p = 0.004), and PAS (2.14, p < 0.05), with large effect sizes (height, d = 3.04; 6MWT, d = 1.87, H/FL d= 1.845 and PAS d = 1.15).
