  1. Obs. = Observed number of second primary cancers; SIR = standardised incidence ratio; CI = confidence interval; CNS = central nervous system; PCT = plasma cell tumours. Analysis by period of first diagnosis was restricted to five years of follow-up to allow more consistent comparisons across time. SIRs shown in normal bold font indicate significantly increased risk; SIRs shown in bold italics indicate significantly decreased risk. Estimates are not shown for Brain & CNS for the periods 1982-1986 and 1992-1996 due to observed cell counts of less than 5.
