Dose fractionation and BED*
54 Gy, 3 fractions (BED = 151.2 Gy)	13 (52%)
50 Gy, 4 fractions (BED = 112.5 Gy)	9 (36%)
36 Gy, 3 fractions (BED = 79.2 Gy)	2 (8%)
42 Gy, 3 fractions (BED = 100.8 Gy)	1 (4%)

*Biological equivalent dose is calculated per (1), assuming α/β ratio of 10 for tumor (n  = number of fractions, d = total dose).
