Table 1 shows that RBC aggregation was positively correlated with BMI (p-trend = 0.001), hyperlipidemia (p-trend < 0.001), MetS (p-trend = 0.001), blood lipids, and hepcidin (both p-trend < 0.01). On the other hand, %TS was a negatively correlated with RBC aggregation (p-trend = 0.001). Here, HAMP is linked to hyperlipidemia.
