Table 4.

Combined analysis: parameters TD₅₀, m and n (95% CI) in terms of mean dose (n = 1) and with n unrestricted for flow data one year post-RT. Goodness-of-fit is expressed as the deviance (Δ).

	mean dose (n = 1)	full LKB (n unrestricted)
TD₅₀ (Gy)	39.9 (37.3-42.8)	39.4 (33.8-41.8)
m	0.40 (0.34-0.51)	0.42 (0.36-0.58)
n	1	1.13 (0.75-14.3)
Δ	339.2	340.6

Abbreviation: CI = confidence interval; TD₅₀ = the uniform dose to the whole organ resulting in 50% complication probability; m = slope of the complication probability curve; n = volume dependency parameter.
