When comparing stroke patients who received NAC to those who didn't, only one blood marker related to oxidative stress showed a significant difference between the groups.
Scientific Claim
N-acetylcysteine administration did not significantly improve most oxidative stress biomarkers in the overall ischemic stroke patient group when compared to the control group, with only total oxidant status (TOS) showing a significant difference (p=0.02).
Original Statement
“When comparing control and intervention groups, we found no significant difference between the results of studied parameters except for TOS. The p values corresponding to each test are as following: TAC: P = 0.46, TOS: P = 0.02, MDA: P = 0.44, catalase: P = 0.75, paraoxonase: P = 0.97, and neopterin: P = 0.09.”

Assessment Explanation
The RCT design supports the conclusion that only TOS showed significant difference between groups. The verb 'did not significantly improve' is appropriate for this finding.
