Women with high blood pressure tend to have slightly lower mouth bacteria activity for converting nitrate to nitrite compared to women with normal blood pressure, though this difference isn't quite statistically significant.

Assessment Explanation

The study is observational and reports a trend (p=0.099) without claiming significance. The language 'tended to be lower' appropriately describes the non-significant trend.

Similar Assertions

How well your mouth bacteria convert nitrate to nitrite is related to your resting blood pressure, though this relationship is only marginally significant.

82%

How well your mouth bacteria convert nitrate to nitrite is related to how much your blood pressure drops after eating nitrate-rich food, even when accounting for your starting blood pressure.

81%

Whether a woman is pregnant or not doesn't seem to affect how well her mouth bacteria can convert nitrate to nitrite.

76%

Men tend to have bigger blood pressure drops than women when taking nitrate supplements, even though both groups get similar increases in nitrite levels in their blood.

73%

Women with high blood pressure have much lower levels of nitrite in their saliva than women with normal blood pressure.
