Deciphering the Timing and Impact of Life-extending Interventions: Temporal Efficacy Profiler Distinguishes Early, Midlife, and Senescence Phase Efficacies

Nisi Jiang, Catherine Joyce Arago Cheng, Qianqian Liu, Randy Strong, Jonathan Gelfond, James F. Nelson

The paper introduces a tool to estimate age-specific treatment effects on mortality hazards, applied to mouse data showing varying efficacy of life-extending interventions across lifespan stages.
