Table 4 Multivariate results for association of age, sex, area, income quintile and separation year with cancer count (offset by population count), for first, other and all separations by all and specific cancers (SAS PROC GENMOD-GEE). Results shown are chi-square, associated degrees of freedom (DF) and p-values of score statistics for type 3 GEE analysis.
