01Summary
It outperforms seven baselines in 16 of 18 clinical datasets with a C-index gain of 0.1–0.2. In hepatocellular carcinoma, it proposes PFKFB2 as a prognostic factor with >0.8 literature plausibility and experimentally validates its role in promoting cell proliferation.
Summarised from the original article by an open-source model, then checked automatically: every number and English name must appear in the source. The original article is authoritative.
