  • *Median value and IQR given non-parametric distribution.

  • †Values derived from log-transformed data; n=40 for Nε-(carboxymethyl)lysine and LMWF levels, and n=33 for all other angiogenesis-related biomarkers.

  • LMWF, low-molecular-weight fluorophore; sRAGE, soluble receptor for advanced glycation end products; VEGF, vascular endothelial growth factor; sVEGFR, soluble VEGF receptor.
