An algorithm for direct causal learning of influences on patient outcomes

作者:

Highlights:

• We propose a new algorithm (DCL) to learn the direct causal influences of a target such as a disease outcome.

• DCL uses Bayesian network scoring and a novel deletion algorithm.

• Results show DCL clearly outperforms PC with respect to accuracy and runtime.

• Found SNPs directly causal of LOAD on NISCH & PRKG1 and validated by prior studies.

• Further Validated ER cat. & HER2 status causal of 5 & 10-year breast cancer survival/death, resp.
