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.
