Values are presented as median (interquartile range).

The values of TOS, TAS, OSI were given as μmol H₂O₂ equivalent/L, mmol Trolox equivalent/L, (μmol/L H₂O₂)/(μmol/L Trolox), respectively.

^*p=0.001,

^†p=0.005,

^‡p=0.004,

^§p=0.0001, and

^¶p=0.009 compared with controls;

^**p=0.004 and

^††p=0.006 compared with before ECT values.

TOS, total oxidant status; TAS, total antioxidant status; OSI, oxidative stress index.
