Pre-disease transition validation
Can a locked, transportable model estimate SLE-specific transition risk accurately, fairly, and usefully enough to justify a later mechanism-matched prevention trial?
No model may advance until predictor timing, competing outcomes, leakage, calibration, participant governance, and independent external validation are operational.
Can start now
- Audit cohort provenance, screening logs, predictor timestamps, outcome definitions, and participant overlap.
- Validate the common data dictionary, synthetic fixtures, missingness rules, and reproducible analysis tables.
- Inventory low-cost clinical predictors before adding molecular layers.
- Prepare risk-communication and false-positive-harm review packets for accountable experts and patient partners.
Cannot start yet
- Recruit, disclose individual risk, or label ANA positivity as a high-risk state.
- Test a preventive intervention or use a biomarker to direct care.
- Call case-control discrimination an absolute-risk model.
An independently replicated, calibrated absolute-risk model with net benefit beyond low-cost clinical predictors—or a documented stop decision showing that prevention-trial recruitment is not justified.
A useful failure: It prevents an inaccurate model from creating false-positive surveillance, anxiety, inequity, or an unsafe prevention trial.Inspect roles & ownership
