Kaplan-Meier curves showing PPM1D expression and overall survival in patients with CRC. (A) Patients with high PPM1D expression levels had poorer overall survival compared with patients with low PPM1D expression. Data are representative of 368 CRC tissues (P<0.001). (B) Patients with high PPM1D expression in metastatic lymph nodes had poorer overall survival than patients with low metastatic lymph node PPM1D levels. Data are representative of 74 metastatic lymph node tissues (P=0.009). PPM1D, protein phosphatase, Mg²⁺/Mn²⁺ dependent, 1D; CRC, colorectal cancer.
