Survival analysis (disease-specific survival). Chemotherapy-treated population. Two univariate models. Combination of NPI score and Immunity2 metagene expression

139 triple-negative breast cancer patients		DS-survival HR [95% CI]	p value
NPI score/Immunity2 metagene expression	NPI1-2/HighI2	1
	NPI1-2/LowI2	2.90 [1.51–5.56]	0.001
	NPI3	3.98 [2.00–7.92]	8.7210-5
NPI score/Immunity2 metagene expression	NPI1-2/HighI2	1
	NPI1-2/LowI2	2.91 [1.51–5.59]	0.001
	NPI3/HighI2	2.31 [0.96–5.57]	0.06

Abbreviations: NPI, Nottingham Prognostic Index; I2, Immunity2; HR, hazard ratio; CI, confidence interval.

NPI = [0.2 × S] + N + G.

S: tumor size (cm).

N: number of lymph nodes involved (0 = 1, 1−3 = 2, >3 = 3).

G: tumor grade according to Elston and Ellis (Grade I=1, Grade II = 2, Grade III = 3).
