Anti-aging interventions affect lifespan variability in sex, strain, diet and drug dependent fashion

Figure 2. Density plots of the age at death of control mice (a) and mice treated with effective anti-aging pharmaceuticals (b). Cox-test for difference between females (solid red line) and males (dashed blue line) in survival with research site as random effect variable: control mice: z = 11.02, p < 0.001; treated mice: z = 6.95, p < 0.001.
