For some stroke patients, NAC treatment significantly improves several blood markers related to oxidative stress and inflammation.

For most stroke patients, NAC treatment didn't significantly change most blood markers related to oxidative stress compared to standard treatment alone.

For some stroke patients, NAC treatment actually made some blood markers related to oxidative stress worse, while improving others.

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.

Taking NAC along with regular stroke treatment lowers a measure of harmful oxidative stress in the blood of stroke patients.

Stroke patients who only received standard treatment showed no significant changes in blood markers related to oxidative stress over the first 24 hours of treatment.
