The threshold of 10%* as excessive health expenditure is the standard from the Ministry of Health and Welfare in Korea, while that of 40%** is from WHO. As WHO recommended using flexible threshold according to cultural and national background differently, we performed further statistical analysis using 10% on paper, although we also performed another statistical analysis in online supplementary materials.
