Figure 3. Analysis of the correlation between the expression level of PNPO and the overall survival (OS) of patients with IDC. PNPO expression was classified into two groups: PNPO low and PNPO high. The OS rate of 127 IDC patients was estimated by Kaplan-Meier analysis. The survival plots of IDC patients are shown. (A) Patients with low and high expression of PNPO. a vs. b: P=0.2575. (B) Patients with low and high expression of PNPO in age low (≤60 years) and high (>60 years) groups. a vs. b: P=0.6034; c vs. d: P=0.5127; a vs. c: P=0.5514; b vs. d: P=0.9694; a vs. d: P=0.5215; b vs. c: P=0.5442. (C) Patients with low and high expression of PNPO in non-metastasis and metastasis groups. a vs s. b: P=1.0000; c vs. d: P=0.3299; a vs. c: P=0.2024; b vs. d: P=0.0128; a vs. d: P=0.0385; b vs. c: P=0.1782. (D) Patients with low and high expression of PNPO in small (≤2 cm) and large (>2 cm) tumor groups. a vs. b: P=1.0000; vs. d: P=0.3339; a vs. c: P=0.3527; b vs. d: P=0.0459; a vs. d: P=0.1953; b vs. c: P=0.3173. (E) Patients with low and high expression of PNPO in low grade (1+2) and high grade (3) groups. a vs. b: P=0.1169; c vs. d: P=0.4070; a vs. c: P=0.2024; b vs. d: P=0.2542; a vs. d: P=1.0000; b vs. c: P=0.6708. (F) Patients with low and high expression of PNPO in early (I+II) and later (III+IV) stage groups. a vs. b: P=1.0000; c vs. d: P=0.5600; a vs. c: P=0.0253; b vs. d: P=0.0009; a vs. d: P=0.0112; b vs. c: P=0.0223. (G) Patients with low and high expression of PNPO in ER low and high expression groups. a vs. b: P=0.4315; c vs. d: P=0.4520; a vs. c: P=0.4328; b vs. d: P=0.4912; a vs. d: P=0.7461; b vs. c: P=0.3919. (H) Patients with low and high expression of PNPO in PR low and high expression groups. a vs. b: P=0.6074; c vs. d: P=0.6547; a vs. c: P=0.5514; b vs. d: P=0.4993; a vs. d: P=0.3594; b vs. c: P=1.0000. (I) Patients with low and high expression of PNPO in HER2 low and high expression groups. a vs. b: P=0.4549; c vs. d: P=0.9261; a vs. c: P=0.3404; b vs. d: P=0.8380; a vs. d: P=0.3404; b vs. c: P=0.9143. (J) Patients with low and high expression of PNPO in less (≤10) and more (>10) Ki-67 positive groups. a vs. b: P=0.9372; c vs. d: P=0.6048; a vs. c: P=0.4096; b vs. d: P=0.7686; a vs. d: P=0.9474; b vs. c: P=0.3711.
