10	Indeterminate vs. Negative	2.72	1.18 - 6.25
10	Positive vs. Negative	0.75	0.35 - 1.62
20	Indeterminate vs. Negative	2.16	1.24 - 3.77
20	Positive vs. Negative	1.15	0.66 - 1.98
30	Indeterminate vs. Negative	1.73	1.11 - 2.68
30	Positive vs. Negative	1.76	1.17 - 2.65
40	Indeterminate vs. Negative	1.38	0.76 - 2.48
40	Positive vs. Negative	2.69	1.73 - 4.19
50	Indeterminate vs. Negative	1.10	0.46 - 2.64
50	Positive vs. Negative	4.13	2.23 - 7.65
60	Indeterminate vs. Negative	0.87	0.26 - 2.93
60	Positive vs. Negative	6.33	2.70 - 14.85

Odds ratios are presented relative to patients with same left ventricle ejection fraction and negative microvolt T-wave alternans status.
