  Activity limitation only (n = 38) Severe health difficulty only (n = 351) Chronic condition only (n = 1580) Elevated service use only (n = 2110) Two or more indicators (n = 3117)

  1. All comparisons made pair-wise with those classified by two or more indicators. By definition, individuals in the uniquely defined indicator groups often did not possess a particular characteristic; in such cases, significance of the difference with the "two or more indicators" group was not assessed. Statistical significance was adjusted for multiple comparisons (significant differences, *p < 0.0125).
  2. Effects sizes (standardized increments) refer to comparisons made with "two or more indicators" group
  3. ... Effect sizes (standardized increments) not calculated when proportion was zero in one of the two groups.
  4. These estimates should be interpreted with caution due to marginal coefficient of variation (CV, 16.6–33.3%). Estimates whose CV is greater than 33.3% are unacceptable for publication and have been suppressed (U)
