When people used the special mouthwash, their blood pressure went up but their heart rate didn't change, which suggests the effect is specific to blood pressure regulation.
Scientific Claim
In healthy young adults, the blood pressure increase from disrupting oral nitrate-reducing bacteria was not accompanied by changes in heart rate, suggesting the effect is specific to blood pressure regulation.
Original Statement
“There were no changes in HR as estimated using all three distinct techniques: clinic ΔHR 2.0 ± 1.7 bpm, p = 0.25; home ΔHR 1.3 ± 1.0 bpm, p = 0.18; and ambulatory ΔHR 2.0 ± 1.4 bpm, p = 0.17 (data not shown).”

Assessment Explanation
The study design supports describing the lack of change in heart rate alongside blood pressure changes. The language 'was not accompanied by changes' appropriately reflects the observed pattern without implying causation.
More Accurate Statement
“In healthy young adults, the blood pressure increase following disruption of oral nitrate-reducing bacteria was not associated with changes in heart rate, suggesting the effect is specific to blood pressure regulation.”
