Nomogram-based K-M curves of patients with different responses to nCRT. (a) and (b) are the K-M DMFS curves for pCR (P = 0•0059, log-rank test) and non-pCR (P < 0•0001, log-rank test) patient subgroup. (c) and (d) are the K-M DMFS curves for downstaging (ypT0-2N0) (P < 0•0001, log-rank test) and non-downstaging (P < 0•0001, log-rank test) patient subgroup. The numbers of patients at risk for each time step are shown in the bottom. nCRT neoadjuvant chemoradiotherapy; DMFS distant metastasis free survival; pCR pathologic complete response.
