4.4.9. Calculation of Oxidative Stress Score (OSS)
In this calculation, we used cutoff points previously established by our research group for the following markers: LPO ≥ 0.340 mmol/L, SOD ≤ 170 IU/mL, GPx ≤ 5500 IU/L, Cat ≤ 0.9 mmol/L, SOD/GPx ≥ 0.023 and GAP ≤ 190 mmol/L. For each datum outside the cutoff values, one point was awarded, and a sum was made to obtain the OSS. The OSS value is directly proportional to OS levels [
