Effect of Surgical Treatment on Lipid Peroxidation Parameters and Antioxidant Status in the Serum of Patients with Peripheral Arterial Disease

Table 2

Pearson’s correlation coefficients 𝑟₁ and 𝑟₂ for the analyzed parameters before surgery versus 3–5 days (Δ₁) and 7–10 days (Δ₂) after surgery, respectively.

Parameter	𝑟1 (Δ1)	𝑟2 (Δ2)	𝑃 value
MDA	−0.575	−0.516	<0.05
LOOH	−0.671	−0.778	<0.05
FRAP	−0.555	−0.637	<0.05
Thiol groups	−0.664	−0.599	<0.05
Ceruloplasmin	n.d.	−0.682	<0.05

MDA: malondialdehyde; LOOHs: lipid hydroperoxides; FRAP: ferric reducing antioxidant power; and n.d.: no difference.
