6MWT deficit = difference between the minimal distance walked within the 6MWT. MH = Mental health; EA = Emotional Aspects; SA = Social Aspects; V = Vitality; OHS = Overall Health Status; PL = Physical limitations; FC = Functional Capacity. * Correlations with p < 0.05; Bold and underline: moderate correlation.
