Pre-registration
Kidney-dialysis markets with competing providers and outcome-based reimbursement show lower mortality and hospitalisation than single-provider models.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
SUPPORTED if the treatment coefficient has the predicted sign at p<0.10. REFUTED if the opposite sign is significant at p<0.10. Otherwise PARTIAL.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
