Statistical tests showed there was a significant correlation between knowledge and QOL based on utility value (p=0.01), but not with VAS value (p=0.165). These was reinforced by age has a significant correlation with knowledge (p=0.042), also employment status and complications condition has a significant correlation with QOL (p<0.05). Patients with a higher level of knowledge have a better QOL, despite different backgrounds.
