  1. Cumulative rates, the rates for patients aged 0–74 years, are a special form of standardized rates in which equal weights are given for all 5-year age groups up to a defined upper age limit, which in this case is 75 years. For each year included in the present study, age-specific rates were computed and multiplied by the length of the age group in years (5 years). These were then summed to derive the cumulative incidence rates
  2. ASRIC age-standardized rate of incidence by 2000 Chinese standard population, ASRIW age-standardized rate of incidence by 1985 Segi’s world standard population
