Scatter diagram of the left common iliac vein compression degree in all patients. (a) Left common iliac vein compression degree in the female group (n = 228, 24% [8%, 42%]). (b) Left common iliac vein compression degree in the male group (n = 272, 9% [3%, 30%]). We observe that a compression degree of ≥25% is more common among young women than in men (χ2 = 17.85, P < 0.01).
