The antioxidant NAC didn't change the size of the heart muscle in mice with heart failure.
Scientific Claim
N-acetylcysteine treatment did not significantly affect left ventricular mass in a mouse model of heart failure with cardiac-specific MST-1 overexpression.
Original Statement
“LV mass did not significantly differ between WT and MST‐1 mice treated with saline vehicle (P = 0.99; Fig. 1).”

Assessment Explanation
The claim correctly states the lack of significant effect on heart mass in this specific mouse model without overgeneralizing.
More Accurate Statement
“N-acetylcysteine treatment was not associated with significant changes in left ventricular mass in a mouse model of heart failure with cardiac-specific MST-1 overexpression.”
