Table 3. Clinical dose response data showing both the relative risk for brain metastases at 3 years and the tumour control probability.

Dose in 2.5 Gy fractions	Reference	RR for brain metastasis (at 3 years)	TCP (no reseeding)	TCP (maximal reseeding)
11.5	[4]	0.760	0.240	0.418
25.5	[4]	0.520	0.480	0.703
31.2	[4]	0.340	0.660	0.917
36.5	[4]	0.270	0.730	1.000
25.0	[5]	0.543	0.457	0.676
33.8	[5]	0.481	0.519	0.749

RR, relative risk; TCP, tumour control probability.
