abstract
This article walks through how to estimate conditional average treatment effects (CATEs) with right-censored time-to-event outcomes using the function causal_survival_forest (Cui et al., 2023) in the R package grf (Athey et al., 2019, Tibshirani et al., 2024) using data from the National Job Training Partnership Act.

CAST: Time-Varying Treatment Effects with Application to Chemotherapy and Radiotherapy on Head and Neck Squamous Cell Carcinoma
CAST fits quadratic and spline curves through ten horizon-specific causal forest estimates, reporting a chemotherapy survival benefit in 2,651 head and neck cancer patients that peaks between 50 and 65 months and then declines.
