^†𝑟=0: no correlation, 𝑟=+1/(−1): perfect positive/negative correlation.
*Significant correlation, 𝑃 < 0.001.
PCS: physical component summary score, PF: physical function, RP: role-physical, BP: bodily pain, GH: general health, MCS: mental component summary score, VT: vitality, SF: social function, RE: role-emotional, and MH: mental health.
