Such analysis was carried out on all 46 measured parameters: red cells count, Hemoglobin, HCT, MCP-1 and MIP-1ß were the only parameters able to significantly discriminate proliferating IH from regressing IH showing a ROC area >0.80 and a strongly significant p value (Fig. 2). The gene discussed is CCL2; the disease is isolated hemihyperplasia.
