| Variable | Exp(β) | (95% Confidence Interval) |
|---|---|---|
| Intracoronary adenosine | 2.69 | (2.16 – 3.77) |
| Cardiac workb | 1.16 | (1.11 – 1.20) |

| Arterial O2 contentb | 0.49 | (0.45 – 0.56) |
| Squared arterial O2 contentb | 1.12 | (1.09 – 1.20) |
a
Intraclass correlation coefficient = 0.210, indicating 21.0% of the total variation is accounted for by sheep fetus
b
Variables are mean-centered and scaled to represent a one unit change.
