Clinical Classification of Chronic Venous Disease C0: No visible or palpable sign of venous disease C1: Telangiectasias (spider veins) or reticular veins (veins that feed spider veins) C2: Varicose veins C3: Edema (swelling) C4: Changes in skin and tissues underneath the skin A: Pigmentation or eczema B: Thickening, hardening, swelling, redness, inflammation, scarring C5: Healed venous ulcer C5: Healed venous ulcer C6: Active venous ulcer It is important to note that some potential complications of venous disease, such as deep vein thrombosis, can occur even in people who have no overt signs corresponding with any of the aforementioned stages
Anti inflammatory and antioxidant signaling Evidence sources : cell and animal work, narrative and mechanistic reviews Confidence : moderate on signaling changes Main caveats : shifts in biomarkers are not the same as demonstrated clinical benefit
Amplification reactions were run in an ABI 7900HT Fast Real Time PCR machine with an initial melting period of 95 C for 5 min then 45 cycles of 10 s at 95 C, 30 s at 60 C
Data analysis Data were analyzed using linear regression mixed models with item-specific and participant-specific random effects 65
