Correlation and multiple linear regression analysis between COMPASS-31 score and several independent variables. The r values and P values are labeled. A multiple linear regression model was used to distinguish any factors that were independently related to the COMPASS-31 score, and Pmulti indicates the statistical result. A value of P < 0.05 was considered significant. * Asterisks mark the variables that are significantly correlated with COMPASS-31 scores in the correlation analysis; COMPASS-31 scores were correlated with the number of attacks, disease duration, EDSS, segments of spinal cord lesions (thoracic, total), HADS-A, HADS-D, PSQI, and FSS. # This symbol indicates that the variable was independently correlated with the COMPASS-31 score in the multiple linear regression model. EDSS, segments of total spinal cord lesions, and FSS were the independent correlated factor. COMPASS-31, Composite Autonomic Symptom Score 31; EDSS, Expanded Disability Status Scale; HADS-A, Hospital Anxiety and Depression Scale–Anxiety; HADS-D, Hospital Anxiety and Depression Scale–Depression; PSQI, Pittsburgh Sleep Quality Index; FSS, Fatigue Severity Scale
