Results of likelihood ratio test; baseline model as comparison: cancer specific mortality and all-cause mortality
| Cancer specific mortality | All-cause mortality | |||
|---|---|---|---|---|
| Model 1 (baseline + Charlson categories) | LR chi2(2) = 4.28 | P = 0.12 | LR chi2(2) = 27.56 | P < 0.0001 |
| Model 2 (baseline + comorbidity count) | LR chi2(3) = 2.03 | P = 0.57 | LR chi2(3) = 18.60 | P = 0.0003 |
| Model 3 (baseline + conditions with independent* HR≥1.2)1 | LR chi2(7) = 14.46 | P = 0.04 | LR chi2(9) = 46.23 | P < 0.0001 |
| Model 4 (baseline + all conditions with 20 or more cases) | LR chi2(13) = 19.93 | P = 0.10 | LR chi2(13) = 52.66 | P < 0.0001 |
Baseline model adjusts for following covariates: Age, sex, ethnicity, NZdep, smoking, year of registration, stage, grade and site.
*after adjustment for patient and colon cancer related factors
1For cancer specific mortality this included previous myocardial infarction, congestive heart failure, cerebrovascular disease, other neurological conditions, diabetes, renal disease, chronic respiratory disease. For all cause mortality this included all these conditions and also cardiac arrhythmias, and peripheral vascular disease.
