Notes: Pearson/point‐biserial/eta correlation coefficients (*Spearman correlation coefficients for non‐normal distributed or ordinal scale data) between putative explanatory variables and the SF‐36 physical (PCS) and mental (MCS) components scores.

Abbreviations: BPI, brief pain inventory; CNS, central nervous system; ERT, enzyme replacement therapy; HADS, Hospital Anxiety and Depression Score; Lyso‐Gb3, globotriaosylsphingosine; MCS, mental component summary; NYHA, New York Heart Association; PCS, physical component summary; PNS, peripheral nervous system; VAS‐F, fatigue on visual analog scale; VAS‐P, pain on visual analog scale; α‐GAL, alpha galactosidase.

Bold values indicate significant associations by the <0.001 threshold.
