Fig. 2From: Prognostic significance of the Naples prognostic score in colorectal cancer patients undergoing curative resection: a propensity score matching analysisKaplan–Meier survival analyses of the high- and low-NPS groups in the overall study population (n = 533). a Overall survival (OS). The OS rate in the high-NPS group was significantly lower than that in the low-NPS group (p < 0.001). b The disease-free survival (DFS). The DFS rate in the high-NPS group was significantly lower than that in the low-NPS group (p = 0.017). c OS after propensity score matching. The OS rate in the high-NPS group was significantly lower than that in the low-NPS group after matching (p = 0.003). d DFS after propensity score matching. The DFS rates of the high and low NPS groups (≥ 7) did not differ to a statistically significant extent (p = 0.058)Back to article page
