  1. Note: * Incidence of medical impoverishment and Intensity of medical impoverishment (IMI) equal d and h in Table 4, respectively; ** Proportion of HIHS and IMI reduced by NRCMS equal f and i in Table 4, respectively;
  2. Distribution analysis indicated that all χ2 and ANOVA results were significant (p < 0.05).
