From: A scoping review of studies using observational data to optimise dynamic treatment regimens
A decision tree containing several possible dynamic treatment regimens (DTRs). Shown are binary covariates (O1, O2), binary treatments (A1, A2), and a terminal outcome (Y) that is a function of patient history. The decisions that map the accumulated patient history to a treatment are represented as the functions d1(.) and d2(.)
