n (participants); Mdn (median); IQR (interquartile range); p (p-value from Mann–Whitney U test, Bonferroni correction p < 0.007); rho (Spearman rho); p† (p-value from Spearman rho, Bonferroni correction p < 0.007); * (p < 0.007); ** (p < 0.001); FES-I (Fall Efficacy Scale-International. 16, no concern about falling; 64, severe concern about falling); Yes (FEI-I Score ≥ 24); No (FES-I Score < 24). FIQ-R (Fibromyalgia Impact Questionnaire Revised. From 0 to 100 indicating the lowest to highest degree of disability due to the disease); EQ-5D-5L Index (EuroQol. 1: the best state of health. 0: death. Negative values indicate conditions worse than death); EQ-5D-5L VAS (0: the worst health. 100: the best state of health).
