Need
Could the goal be reached without buying a product or adding another intervention?
The NST methodology
Trust requires a process people can see.
NST is designed to separate evidence, interpretation, practical guidance, and commercial relationships as clearly as possible.
Research process
From question to useful guidance.
The goal is not to collect the largest number of sources. It is to find the evidence that best addresses the decision and explain it in context.
01
Define the real question
Identify the decision a person is trying to make, the outcome they want, and the context that may change the answer.
02
Gather relevant evidence
Look for appropriate primary research, systematic reviews, consensus guidance, and useful supporting sources.
03
Assess the evidence
Consider study quality, relevance, consistency, limitations, population, outcomes, and the size of any observed effect.
04
Translate with context
Explain what the findings may mean in practice without presenting uncertain evidence as a guaranteed result.
05
Compare realistic options
Evaluate suitability, tradeoffs, cost, usability, alternatives, and whether an intervention or product is needed at all.
06
Review and update
Revisit published guidance when stronger evidence, important corrections, or meaningful product changes become available.
Evidence standards
A source is not the same as an answer.
Evidence must be evaluated for relevance and reliability before it can support a conclusion.
- Does the source directly address the question?
- Who participated, and does that population match the intended reader?
- What outcome was measured, and is it practically meaningful?
- How strong, consistent, and precise are the findings?
- What limitations or conflicts should be made visible?
- Does the conclusion go beyond what the evidence supports?
Recommendations and comparisons
A recommendation comes last. Understanding comes first.
Suitability
Who may benefit, who may not need it, and who should seek qualified professional guidance?
Evidence
Is the claimed benefit supported, plausible but uncertain, or primarily based on marketing?
Tradeoffs
What are the limitations, costs, practical burdens, risks, and reasonable alternatives?
Transparency
Are commercial relationships and the basis for the recommendation clearly disclosed?
Transparency
Commercial support should remain visible.
