*c indicates control group; d/dMTS, low lumbar degeneration-related May-Thurner syndrome; o/oIVCS, other cause iliac vein compression; s/sMTS simple May-Thurner syndrome.
Ps-c means comparison among sMTS and its control group, and so on.
†Bofferroni test was used in the statistical correction of multiple comparisons of means.
