Levels of CgA peptides and selected TA clinical features. Plasma concentrations of CgA₄₃₉, CgA-FRs and VS-1 in the whole group of TA patients (left panels) and in those on PPI therapy (right panels), stratified for vascular enhancement (upper panels), disease activity (middle panels) and vascular progression (lower panels) (see “Methods”). CgA ₄₃₉ full-length chromogranin-A (residues 1–439), CgA-FRs fragments of CgA spanning from the N-terminus to the central region but lacking the C-terminal region, PPI proton-pump inhibitors, VS-1 vasostatin-1
