Table 1. Predicted regression probability for cerebellar PA based on the absolute residual tumor size.

Residual tumor size (cm3)	Tumor regression probability (in %)
0.1	98.91
0.5	94.06
1	88.16
2	76.50
3	65.03
4	53.75
5	42.64
6	31.71
7	20.47
8	10.39

The values in this table are derived from the PA-regression-function provided by Eq (7) and use an estimate for the critical tumor size of 9 cm³. The PA-regression-function is also illustrated in Fig 5.
