Hazard ratios for death by age and stage. Univariable and Cox proportional hazard ratios demonstrating the association between advanced age and stage with an increased risk of death.

Factor	Cox proportional hazard ratio	95% confidence interval	𝑃 value
Age (1st compared to 3rd quartiles, 54.5 versus 73.5 years)	3.28	1.51–7.11	0.003*
Stage III (compared to Stages I and II)	4.75	1.16–19.4	0.03*
Stage IV (compared to Stages I and II)	9.13	1.76–47.45	0.009*

*Statistically significant with 𝑃 < or = 0.05.
