  2. Abbreviations: CI, confidence interval; ED, eating disorder
  3. Notes: Age-specific rates per 100,000 are calculated using Statistics Canada national population estimates (excl. QC) from 2010 to 2022, with 95% CIs. Patients with a gender other than male or female have been excluded (n = 17) due to small sample sizes
  4. Hospitalization data with small counts between one and four as well as rates that would allow for derivation of small counts have been presented as a range
