Table 6:

Characterization of sensitivity parameters under three scenarios (all are ratios that compare subgroups U = 1 to U = 0): γ_A (comparing odds of RT and/or CT), ${\gamma }_Y^{(1)}$ (compares odds of zero-cost), and ${\gamma }_Y^{(2)}$ (compares geometric mean cost in the first interval among those with nonzero cost).

Scenario	Confounding level	γA	${\gamma }_Y^{(1)}$	${\gamma }_Y^{(2)}$
1	Low	1.11	0.820	1.025
2	Moderate	1.28	0.719	1.105
3	High	1.65	0.613	1.220
