Table 4.

Median (IQR) values of studied parameters of oxidative stress in patients receiving or not prostacycline treatment.

	Patients with PC (n = 14)	Patients without PC (n = 31)	p value
TAC (mM)	0.48 (0.38-0.65)	0.64 (0.42-0.76)	0.15
MDA (μM)	2.19 (1.63-3.35)	3.32 (1.30-4.02)	0.47
CAT (U/L)	1.46 (1.16-1.90)	1.29 (1.19-2.37)	0.85
SOD (%)	79.16 (74.79-82.48)	79.89 (77.23-84.80)	0.38

TAC: total antioxidant capacity; MDA: malondialdehyde; CAT: catalase activity; SOD: superoxide activity; PC: prostacyclines; p value refers to Mann-Whitney U test.
