Figure 4.
Mitotic age of tumor tissues and cancer survival. (a) Higher averaged estimated mitotic ages of tumor tissues are associated with lower 5-year survival rates across the 13 cancer types in the training and testing data with r = −0.6 (P = 0.029) (left panel). The correlation is weaker and not significant for mitotic age of normal adjacent tissues (right panel). (b) Higher mitotic age is associated with worse survival in some cancers.
