β Log-Transformed (95% CI)^{a} | Exp. (β)^{b} | P Value | β Log-Transformed (95% CI)^{a} | Exp. (β)^{b} | P Value | |

Visual collateral score per 1 point | −0.49 (−0.61 to −0.37) | 0.60 | <.001 | −0.59 (−0.71 to −0.47) | 0.54 | <.001 |

Quantitative collateral score per 10% | −0.13 (−0.16 to −0.099) | 0.88 | <.001 | −0.14 (−0.18 to −0.11) | 0.87 | <.001 |

**Note:**—Exp. (β) indicates exponent of β.↵a Due to the non-normal distribution of follow-up infarct volume, a log +1 transformation was performed to best fit the assumptions associated with the linear regression model.

↵b Exponent of β was calculated to determine the relative difference of follow-up infarct volume with an increase in collateral scores.
