> "432 Hz tuned music was associated with a slight decrease of mean (systolic and diastolic) blood pressure values (although not significant)"

I can see why this line is fine to some and bothersome to others.

Strictly, it's just describing their results. No problem. The numbers are what they are.

On the other hand, why draw attention to the difference in means, when they are about to tell you not to take it very seriously?

This version avoids that:

"432 Hz tuned music was not associated with a significant difference in mean (systolic and diastolic) blood pressure values"

Maybe it's my age, origin, or personality, but I prefer this version.
