Cumulative survival curves of mortality risks with respect to different concentration groups of galectin-3 and VCAM-1 after adjusting for galectin-3, VCAM-1, albumin, age, CRP, nPCR, and smoking during follow-up. (A) The group with combined higher concentrations of galectin-3 (>29.5 ng/mL) and VCAM-1 (>1546.9 ng/mL) showed higher risks for all-cause mortality as compared to the reference group (galectin-3 < 29.5 ng/mL and VCAM-1 < 1546.9 ng/mL). (B) The group with combined higher concentrations of galectin-3 (>29.5 ng/mL) and VCAM-1 (>1546.9 ng/mL) showed greater CV mortality risks as compared to the reference group (galectin-3 < 29.5 ng/mL and VCAM-1 < 1546.9 ng/mL). The interaction analysis between serum galectin-3 and VCAM-1 remained statistically significant for all-cause mortality (p < 0.01) and CV mortality (p = 0.039), respectively. VCAM-1 = vascular cell adhesion molecule 1; CRP = C-reactive protein; nPCR = normalized protein catabolic rate.
