  1. Data are shown as median (interquartile ranges; Q1-Q3)
  2. aMedical costs were assessed in Korean Won (KRW), and were translated into US dollars ($USD) using a currency exchange rate of 1123 KRW/$USD
  3. Healthcare utilization was compared between the PH subgroups using the number of hospitalization, total duration of hospital stay, and number of outpatient department (OPD) visits. Medical expenditure was compared using the total medical costs, cost for testing, and cost for medications. The outcome parameters were annualized and averaged within each PH subgroup
  4. Abbreviations: same as Table 1
