Kaplan–Meier overall survival (OS) curves for patients with unresectable colorectal cancer based on low and high miR-124-5p expression levels in formalin-fixed paraffin-embedded (FFPE) samples. FFPE samples were obtained from surgery or biopsy for histological diagnosis. Kaplan–Meier plots showing estimates of OS probabilities grouped according to miR-124-5p expression levels in a completely independent set of colorectal cancer patients. The dotted line curve represents samples that expressed high levels of miR-124-5p (above median), whereas the black line curve corresponds to samples that expressed low levels of miR-124-5p (below median). Discontinuations of observations were indicated by spines on the lines. Comparisons between each group were performed with the log-rank test.
