Notes: (1) Data subject to censoring marked by * (see footnote). (2) Previously censored data based on fewer than 10 deaths have not been reported. However, the five year age group specific mortality rates are now so low that in some cases there are fewer than 10 deaths reported in uncensored groups. Hence only censored groups with more than 100 life years of observation are included. (3) The 1983–85 cohort overestimates the hazard rate due to reduced ascertainment of the cases (see text). (4) The standard error of all the 0–1 year age group hazard rates is approximately 10 per thousand, for the 1–5 year group it is approximately four per thousand rising to six per thousand for the 25–30 year group. (5) Entry marked † has no deaths reported at the time of analysis so no rate can be calculated.
