Discussion of Assessing Heterogeneity of Treatment Effect, Estimating Patient-Specific Efficacy, and Studying Variation in Odds ratios, Risk Ratios, and Risk Differences

Hi @f2harrell,

A new RCT just published on JAMA applied a causal forest method to estimate conditional average treatment effects at the levels of the individual (Figure 3B).

It reminded me of these plots in your work:

Would you mind discussing potential advantages or pitfalls of causal forests vs. your approach? Thanks.
