Multivariate Cox regression hazard model for time to recurrence for the composite covariate of eIF4E and p4E-BP1

Prognostic indice HR 95% CI P value
Grade 1 and 2 1
Grade 3 and 4 3.3 2.0-5.2 < 0.001
Stage I and II 1
Stage III and IV 2.3 2.3-3.6 < 0.001
eIF4E-p4E-BP1 covariate negative 1
eIF4E-p4E-BP1 covariate positive 4.2 2.1-8.6 < 0.001

Tumour size and vascular invasion were also entered into the model but were not considered significant at this step. P < 0.05 denotes significance.
