Protein profiles across fibrosis grades showing the top candidates at discriminating grade 1 from grade 2, with DIGE (left) and iTRAQ (right). Proteins shown: DIGE spots 478 (complement factor H, haptoglobin, serum amyloid P-component, dermcidin), 635 (immunoglobulin J chain, desmoplakin, junction plakoglobin, dermcidin), and 631 (desmoplakin, immunoglobulin J chain, actin cytoplasmic 1, junction plakoglobin); iTRAQ proteins 25 [serine (or cysteine) proteinase inhibitor, clade C (antithrombin), member 1] and 54 [serine (or cysteine) proteinase inhibitor, clade A, member 7]. Vertical bars indicate 95% confidence intervals
