Serum Mac-2BP protein levels in patients and controls. Serum levels of Mac-2BP were assayed using an ELISA test. A, a Mann-Whitney U test demonstrates that serum Mac-2BP levels are significantly higher in patients than controls (p < 0.001). B, a Kruskal-Wallis one-way analysis of variance test shows a significant difference in Mac-2BP levels in NET patients with no metastases and small, intermediate, and large volume liver metastases (p = 0.024). Bars indicate median value for the group.
