Table 3 Results of likelihood ratio test; baseline model as comparison: cancer specific mortality and all-cause mortality

From: The effect of comorbidity on the use of adjuvant chemotherapy and survival from colon cancer: a retrospective cohort study

  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
  1. Baseline model adjusts for following covariates: Age, sex, ethnicity, NZdep, smoking, year of registration, stage, grade and site.
  2. *after adjustment for patient and colon cancer related factors
  3. 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.
