Kaplan-Meier survival functions in lymph node negative and positive subjects according to rs2279115 genotype. Overall survival based on 786 subjects with total time at risk 5808.75 years. A shows lymph node negative subjects and B shows lymph node positive subjects. Numbers at risk at the end of the 10-year analysis period were A: 103 (AA), 146 (AC), 79 (CC) and B: 38 (AA), 54 (AC), 18 (CC). Hazard ratios (95% CI) for A were 0.97 (0.73, 1.30), p = 0.85 and for B were 1.20 (0.88, 1.64), p = 0.24.
