Randomized trial enhances predictive modeling accuracy using counterfactual data in healthcare, indicating improved outcomes.

This study aims to enhance healthcare prediction models using a novel method that generates counterfactual data.
Proposed the cycle counterfactual residual generative adversarial network (CCR-GAN) for data generation.
Evaluated CCR-GAN on two datasets: stroke prediction (4,886 patients) and hemodialysis (1,229 patients).
Conducted ablation studies to assess utility, privacy, realism, and actionability of generated counterfactuals.
CCR-GAN improved predictive modeling accuracy on stroke and hemodialysis datasets compared to baseline methods.
Achieved competitive privacy protection with the lowest scores in attribute inference and membership inference tests.
Generated counterfactual data maintained a certain degree of realism while enhancing model accuracy.
