Survival analysis demonstrates prognostic utility of colorectal cancer mucosal microbiota clustering. Kaplan–Meier curves illustrating the difference in disease-free survival in groups stratified by CRC mucosal abundance of microbiota (a cluster 1 microbiota; b cluster 7 microbiota) and by established prognostic factors (c AJCC stage; d tumour differentiation). Time is measured in months since primary tumour resection. For microbiota clusters, individuals were split at the proportional median and classified as “low” (red) and “high” (blue) expressors of each cluster of microbiota.
