¶ How to Compare Interventions (Facets)
We try to make every intervention filterable (or at least scannable) by:
- Evidence level (human outcomes > mechanistic > anecdote)
- Effect domain (sleep latency, VO₂max, LDL‑C, HbA1c, HRV, etc.)
- Risk level (low / moderate / high) + common adverse effects
- Cost (one-time + recurring) and time burden
- Complexity (beginner → advanced) and required equipment
- Time-to-effect (acute / weeks / months)
- Population constraints (pregnancy, anticoagulants, CKD, etc.)
- Measurement readiness (what you should track to know it’s working)
