Quality Of Life In Rheumatoid Arthritis: Cross-National Comparison Study Between US and South Korea

Abstract

Quality of life (QOL) is a well-established outcome for rheumatoid arthritis (RA) trials. To perform trials with QOL as an outcome involving many countries, it is valuable to compare QOL measures across countries. The objective of this study was to compare health-related quality of life (HRQOL) of rheumatoid arthritis (RA) patients between United States (US) and South Korea.
