Machine learning models estimate counterfactuals in IBD trials

Researchers have developed machine learning models to create virtual control arms for clinical trials, specifically in inflammatory bowel disease studies. These models, trained on external data, predict counterfactual outcomes for patients in single-arm trials, potentially reducing the need for extensive patient recruitment. A gradient boosted prediction model, LGBM, showed promising results by closely aligning with estimates from propensity score matching, supporting the use of virtual controls as a cost-effective alternative.
