a
Only patients with complete data for all variables were included in the multivariate analysis. This cohort includes patients referred with stage ib–iii disease (that is, excluding stage ia). The outcome variable is treated versus not treated.
b
Only variables retained in the final multivariate model are shown.
c
By likelihood ratio chi-square test.
d
Cohort year was fixed in the main effects models.
e
“No” when score on the Charlson comorbidity index was 0; “Yes” when score was ≥1.
f
Only variables that had significant interactions with year are shown.
ci = confidence interval; qeii hsc = QEII Health Sciences Centre; cbrh = Cape Breton Regional Hospital.
