Simulation parameters

Simulated Measure	Parameter	Definition
True Vital Status	Death Prevalence:	The true death status for each simulated patient was generated as X∼B(1000,p), where p ranged from 50 to 98% in 2% increments
Vital Status per Test	Test Sensitivity:	For patients with a true death status of 1, the Test indicator was generated as X∼B(1000,p), with p set to 100% across conditions, representing a Test with perfect Sensitivity
	Test Specificity:	For patients with a true death status of 0, the Test indicator was generated as X∼B(1000,p), with p set to 100% across conditions, representing a Test with perfect Specificity
Vital Status per Gold Standard	Gold Standard Sensitivity:	For patients with a true death status of 1, the Gold Standard indicator was generated as X∼B(1000,p), with p ranging from 90 to 99% in 1% increments
	Gold Standard Specificity:	For patients with a true death status of 0, the Gold Standard indicator was generated as X∼B(1000,p), but was modeled as p = 100% for all conditions, reflecting our assumption that if NDI identifies a patient as deceased, they are deceased
