Short answer

Not a single study

No clear answer.

The article covers a research area rather than reporting a specific new paper, so there is no single study to check it against.

Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim by claim

What the story asserts. With no source study, there is nothing to check these against.

Claim 1 of 5Not checkedA study led by researchers at Washington University School of Medicine in St. Louis, Nationwide Children's Hospital, and King's College London created a map of human immune aging that helps decode different aging trajectories.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 2 of 5Not checkedThe findings, published in Immunity, show that a ratio between two immune cell types can reveal whether someone stays healthy or may face a risk of future disease.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 3 of 5Not checkedThe researchers analyzed approximately 12.4 million individual immune cells from the blood of 2,609 mainly healthy adults ages 20 to 90-plus across eight cohorts in North America, the United Kingdom, Asia and Australia.View evidenceHide evidence

As statedapproximately 12.4 million individual immune cells; 2,609 adults; eight cohorts

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 4 of 5Not checkedUsing a smaller dataset and a computer model, the team applied blood-protein traces to about 50,000 UK Biobank participants to estimate each person's position on the immune-cell spectrum.View evidenceHide evidence

As statedabout 50,000 participants

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 5 of 5Not checkedHealthy adults whose immune systems leaned heavily toward granzyme B cells at baseline had a higher risk of death a decade later and were more likely to develop chronic conditions including type 2 diabetes, hypertension, liver disease, and renal failure.View evidenceHide evidence

As stateda decade later; over the following decade

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.
