The Standard on Health Science

Health coverage is where the gap between a study and a headline is widest. Our job is to keep relative risk, absolute risk, and study design visible — because that is where most health claims quietly collapse.

What this field actually measures

Relative vs absolute risk

Proportional change versus change in actual incidence.

ReferenceA '50% increase' on a 2-in-10,000 baseline is 1 additional case per 10,000.

LimitHeadlines print the first number. The second one is the one that matters to you.

Study design hierarchy

Randomised trial, cohort, case-control, observational.

ReferenceObservational nutrition and lifestyle findings routinely fail to replicate in randomised trials.

Number needed to treat

How many people must receive an intervention for one to benefit.

ReferenceThe most honest single figure in clinical communication, and the least quoted.

Evidence & metrics

The published work behind the numbers above, and the public datasets you can open to check us. If a claim can’t be traced here, we don’t print it.

  • Which consumer health metrics are validated against clinical outcomes?
  • What is the real-world benefit of continuous monitoring for healthy adults?

What we won’t say

We will not report a relative risk without the absolute one. That omission is how a rounding error becomes a scare.
