Table 2.

Univariate analysis of CT-derived features and clot burden (n = 96). Values represent coefficients (positive value indicates a positive relationship to clot burden; negative values indicate a negative relationship to clot burden). Highlighted cells indicate coefficients with p-values ≤ 0.05.
