  • Number of cases in parentheses.

  • * P value derived from χ2 value for linear trends.

  • Ill-defined conditions includes deaths attributable to symptoms and signs for which no other classifiable diagnosis can be recorded (7800–7999). Excludes SIDS (7980) and respiratory failure (7991).

  • Percentage change derived from difference between 1992 and 1996 proportionate mortality ratios.
