CCL2 and Patent ductus arteriosus: Our data show that although raw value of MCP-1 did not show significance when correlated with the different clinicopathological parameters in PDA (Table 1) or IPMN patients groups, patients with BMI ≥ 37.5 averaged higher log MCP-1 values than patients with a BMI < 37.5 when using recursive partitioning analysis.
