FIGURE 4. NRFS by lymph node metastasis status at end of primary treatment. Intergroup differences: (1) vs. (2), P = 0.04; (1) vs. (3), P = 0.006; (2) vs. (3), P = 0.3; CoxMantel test. Survival curves are cut at 200 mo, when 15 patients were still under observation for this outcome (patients in follow-up: 141 at 5 y, 55 at 10 y, 8 at 20 y).
