Meanwhile, there was no association (p>0.05) between the quality of life of patients in the domains of physical function (p=1.000), physical role (p=0.208), pain (p=0.151), general health (p=0.308), social function (p=0.195), vitality (p=0.389), and mental health (p=0.255) with depressive symptoms in RA patients.
