Fig. 2. (A) Disease-free survival curves for patients with N ratios of 0%~25%. (B) Overall survival curves for patients with N ratios of 0%~25%. Solid line, XPRT arm; dotted line, XP arm. XP = capecitabine plus cisplatin; XPRT = concurrent chemoradiotherapy with XP; N ratio = the ratio of metastatic lymph nodes to examined lymph nodes.
