The Claim

In normotensive Caucasians, the presence of SGK1 major alleles is associated with a non-significant trend toward higher systolic blood pressure under high-salt intake conditions, with mean systolic blood pressure values of 109.2 mmHg compared to 105.3 mmHg, suggesting that a genetic influence on salt sensitivity may be present in the general population but is currently undetected due to low blood pressure variability requiring larger sample sizes.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

People of Caucasian descent with a certain common gene version might see their blood pressure rise a little when they eat a lot of salt, but the change is so small that we can’t be sure it’s real yet — we’d need to study more people to find out for sure.

See the scientific wording

In normotensive Caucasians, SGK1 major alleles show a non-significant trend toward higher systolic blood pressure on high-salt intake (mean difference of 109.2 mmHg vs. 105.3 mmHg), suggesting the genetic effect on salt sensitivity may exist in the general population but requires larger samples to detect due to smaller BP variability.

What the research says

1 study
  1. Study: POLYMORPHISMS IN THE SERUM- AND GLUCOCORTICOID-INDUCIBLE KINASE 1 GENE ARE ASSOCIATED WITH BLOOD PRESSURE AND RENIN RESPONSE TO DIETARY SALT INTAKE

    The study found that some people’s genes make their blood pressure rise a little more when they eat a lot of salt, even if they don’t have high blood pressure — just like the claim says, but the effect is small and needs more research to be sure.
