Odds ratio for relapse within 5 years as a first event in Stanford ER+a tumors based upon PES expression and NPI-ES expression

Seven samples did not possess proper relapse information and were removed from analysis (leaving 39 ER+ tumors).

ER+ tumorsOdds ratio (95% CI)
PES (P = 0.078)3.6 (0.83–15.55)
NPI-ES (P = 0.027)4.9 (1.13–21.16)
  • a ER, estrogen receptor; PES, prognosis expression signature; NPI-ES, Nottingham prognostic index-expression signature; CI, confidence interval.
