  • Note:—A indicates atherosclerotic; H, hyperplastic; T, thin; R, ruptured; N, normal-appearing; WSSDIV, WSS divergence; WSSGRD, WSS gradient.

  • a The region with the larger value is indicated in parentheses next to the significant P values.

  • b Significant values after a further adjustment for testing multiple hemodynamic variables.

  • c Significant values (adjusted for multiple regional tests).
