Table 2:

ORs for mortality at a BVS threshold of 7 or 6

Fisher Test	OR	95% CI	P Value
7–8 vs ≤6.5	16.17	4.3–69.7	<.001
6–8 vs ≤5	11.50	1.6–503.7	.005
Seydel et al⁷ (7–8 vs ≤6)	13.75^{^a}	4.3–58.6^{^a}	<.001

↵a The OR and CI reported in Seydel et al⁷ used logistic regression and was 14.0 (4.5–43.4). Here we use Fisher exact test instead because of its increased accuracy for sample sizes in this study, which was then also applied to Seydel et al⁷ to make these results comparable. Accordingly, the recalculated OR and CI are slightly different than that reported in Seydel et al⁷.
