Table 1.

Weibull distribution parameters governing simulated population and study data under six simulation scenarios, defined by combinations of three Weibull shape specifications and two log (study/population) hazard ratios β.

Data	Parameter	1:Weibull	2: decreasing cause- specific relative hazard	3: rapidly decreasing cause-specific relative hazard
General population	α⁰	(1.7, 1.7)	(1.5, 2)	(1.5, 4.5)
(n0 = 1000)	λ⁰	(0.0015, 0.0022)	(0.0015, 0.0022)	(1.5 × 10⁻³, 1.5 × 10⁻⁷)
	mean	24.04	17.58	26.96

Study group	α	(1.7, 1.7)	(1.5, 2)	(1.5, 4.5)
