Deviance, and smoking log-hazard ratio (HR) plus standard error (SE) in the different models

model			deviance	log(HR) (SE)
(i)	constant excess risk		10455.93	0.643 (0.083)
(ii)	no excess risk		10542.84	0.188 (0.075)
(iii)	linearly decreasing risk	δ = 0	10455.93	0.643 (0.083)
		δ = 0.05	10441.41	0.718 (0.082)
		δ = 0.09	10438.31	0.708 (0.079)
		δ = 0.10	10438.26	0.705 (0.079)
		δ = 0.11	10438.09	0.704 (0.077)

		δ = 0.20	10439.79	0.672 (0.077)
		δ = 0.25	10444.98	0.660 (0.076)
(iv)	exponentially decreasing risk	p = 0	10455.93	0.643 (0.083)
		p = 0.05	10439.82	0.758 (0.087)

		p = 0.3	10443.87	0.678 (0.078)

All p-values < 0.001, except for model (ii) p = 0.012. Standard errors were calculated using δ and p as given constants.
