Similarly, ROC analysis revealed that plasma proteins, different from those present in UWS, could be helpful in the diagnosis of HT (CTACK: AUC = 0.9, p < 0.0001, IL-3: AUC = 0.82, p < 0.0001, G-CSF: AUC = 0.87, p < 0.0001, HGF: AUC = 0.97, p < 0.0001, IL-8: AUC = 0.89, p < 0.0001, TNF-α: AUC = 0.84, p < 0.0001). The gene discussed is CXCL8; the disease is hematocrit.
