FGF23 and diabetes mellitus: When studying the association between TNFRSF 13B, CCL3, DCN, FGF-23, TRAIL-R2, and TNFRSF10A and classic cardiovascular risk factors, all six markers correlated positively with age (p < 0.001 for each association) and diabetes mellitus (p = 0.002 for TNFRSF13B, 0.02 for CCL3, 0.01 for DCN, 0.002 for FGF-23, <0.001 for TRAIL-R2, and 0.03 for TNFRSF10A), while only TNFRSF 13B and CCL3 correlated negatively with HDL-cholesterol (p = 0.008 and 0.004, respectively).
