↵* Totals in population are less than those in Appendix 1 because non-eligible patients are not represented in this table.
↵† Percentages are based on the 2009 population total in the same cost category.
↵‡ In this second row, one year is 90th–94th percentile and other year could be either 90th–94th or ≥ 95th percentile, because ≥ 95th percentile in all 3 years is separated out for this group only.
↵§ Cost category shown for year of death followed by “–“ in subsequent years.
