Supplementary reproducibility and transparency package for risk-adapted surveillance of lung and bone metastasis in hepatocellular carcinoma

This record provides a governance-compatible reproducibility and transparency package accompanying the manuscript “Risk-adapted surveillance for lung and bone metastasis in hepatocellular carcinoma: international evaluation and prospective two-wave pathway implementation”. The package includes fixed LM/BM threshold definitions, predictor and endpoint dictionaries, denominator maps, missing-data rules, pathway-assignment code, reviewer-oriented analysis-code skeletons, synthetic example data, table-generation workflows, software-environment files, validation scripts, model-card documentation, source-document materials, and a public-calculator manifest. No identifiable patient-level data are included. Controlled-access analytic extracts are governed by institutional approvals, data-use agreements, and confidentiality agreements.
