OS prognostic score in the FAS and the FAS CORRECT populations

FAS Population n = 654		Median OS	6-month OS rate
Score equal to 0,1, 2, or 3 (high benefit from REG, n = 213)	1	9.2	67 %
Score equal to 4 or 5 (moderate benefit from REG, n = 256)	1.78 (1.45–2.18)	5.2	45 %
Score equal to 6+ (low benefit from REG, n = 147)	2.70 (2.13–3.42)	2.5	26 %
FAS-CORRECT Population n =440
Score equal to 0 or 1 (high benefit from REG, n = 185)	1	8.7	64 %
Score equal to 2 (moderate benefit from REG, n = 206)	1.67 (1.34–2.09)	5.5	46 %
Score equal to 3 (low benefit from REG, n = 48)	2.54 (1.79–3.60)	3.4	35 %

Relative weights of the variables found independently related to survival (see Table 3) were added to obtain a total score. This score ranged from 0 to 10, and was then reduced to obtain three categories of patients with significantly different risks of death
