Percent of survival (Kaplan–Meier) in old pHx mice (direct line) and in old sham controls (hatched line) from the age of 20 months. The survival is reduced in old pHx mice in comparison with old sham controls (P<0.01, Log-rank test). High percent of death (90%) occurs at 21 months of age in old pHx mice due specially to the appearance of carcinoma (see Table 2).
