Notes: CI is the Concentration index, HI is the horizontal inequity index, and Con.I denotes confidence interval; 95% confidence interval in parentheses, bold figures denote significance at 5% level of significance; HIs are only reported if CIs are statistically significant at 95% level of significance.
