      limitations
      1. Published aggregate registry statistics; no individual-level records.
      2. Five-year relative survival is not overall survival, a treatment effect, or an individual prognosis.
      3. Year-of-diagnosis trends are not survival curves across follow-up time.
      4. Null age_range means no explicit age subgroup in the source; it does not mean age zero.
      5. No survival age adjustment is asserted unless explicitly documented.
      6. Do not join pooled current estimates onto annual historical trends: registry coverage and cohorts differ.
