Researchers have developed a novel two-stage pipeline, CausalFlow-T, designed to improve treatment effect estimation from incomplete longitudinal electronic health records. The first stage utilizes a DAG-constrained normalizing flow with LSTM encoding for precise counterfactual inference, while the second stage employs an LLM-driven imputer to handle missing data. This combined approach demonstrated superior performance in preserving average treatment effect recovery across various missingness levels compared to statistical baselines. AI
