From: High expression of MMP19 is associated with poor prognosis in patients with colorectal cancer
X-tile analyses of 5-year relapse-free survival were performed using data from the GSE39582 cohort to determine the optimal cut-off values for the MMP19 mRNA levels. a X-tile plots of the training cohort are shown in the left panels, with plots of the matched validation cohort shown in the smaller inset. b The optimal cut-off values highlighted by the black circles in the left panels are shown in histograms of the entire cohort (middle panels); 145 patients were in the MMP19 low expression group, while 351 were in the high expression group, and (c) Kaplan–Meier plots are displayed in right panels, χ2 = 14.070,P < 0.001
