Similarly, there were significantly more women with high CRP level in the IH group (12.3%) than in the reference group (4.7%), (χ2 (1) = 13.5, P < 0.001), and more IH women (10.6%) than reference women (4.3%) with high IL-6 levels, (χ2 (1) = 10.5, P = 0.001). Here, IL6 is linked to isolated hemihyperplasia.
