"textContent": "Under proportional hazards, there is a 1-1 mapping between the HR and difference in cumulative incidence so HR is a fully intent-to-treat quantity. When PH is not satisfied you can include treatment \\times \\log(t) interaction and base inference on any intent-to-treat transformation of those parameters and the underlying survival curve, i.e., cumulative incidence or restricted mean survival time.",
