For healthy young people, eating more or less salt doesn’t seem to make their blood pressure bounce around more or less — their blood pressure stays steady no matter how much sodium they pee out.

Assessment Explanation
The claim uses 'no significant correlation,' which is a statistically cautious phrasing appropriate for observational or cross-sectional data. It correctly avoids implying causation and is limited to a specific population (healthy young adults). The conclusion that sodium intake 'does not directly modulate BPV' is slightly stronger than the correlation data alone can support, as correlation does not prove absence of mechanism — but given the context and population specificity, it is reasonably framed. The wording reflects scientific caution.
More Accurate Statement
“In healthy young adults, urinary sodium excretion is not significantly correlated with any measure of peripheral blood pressure variability, suggesting that sodium intake may not be a direct modulator of blood pressure variability in this group.”

The Impact of High Dietary Sodium Consumption on Blood Pressure Variability in Healthy, Young Adults.
Scientists gave people different amounts of salt and checked if their blood pressure jumped around more — it didn’t. So eating more salt doesn’t make blood pressure more unstable in healthy young adults.
