How we know
what we know.
Every claim in every THRESHOLD planner cites a peer-reviewed source. Every article carries a verification date. When the evidence changes, we update the content and tell you what changed and why. This page explains exactly how that works.
Evidence over opinion.
Always.
THRESHOLD exists because the information people need during the most difficult health transitions of their lives is either locked behind clinical paywalls, buried in academic language, or replaced by wellness content that sounds reassuring but isn't grounded in evidence.
Our commitment is simple: every claim we make traces back to a peer-reviewed primary source. Not a blog post that cited a study. Not an article that referenced another article. The primary source — the original paper, the clinical guideline, the systematic review.
When we can't find the evidence, we say so. When the evidence is mixed or context-dependent, we say that too. We don't simplify for comfort. We simplify for clarity.
"Every claim cites a source. Every source is peer-reviewed. When the evidence changes, we update the planner and tell you what changed and why. This is how trust works."
Where the evidence
comes from.
Our research pipeline searches these databases regularly for new findings relevant to each planner domain. Not social media, not press releases, not industry-funded summaries — primary literature.
Not all evidence
is equal.
When a new study enters our pipeline, we evaluate it against four criteria before it influences any THRESHOLD content:
Is it published in a peer-reviewed journal? Was it funded independently or by an industry with a financial interest in the outcome? Is the journal indexed on PubMed? Preprints and non-peer-reviewed material are noted as such and treated with greater caution.
A study of 40 people does not carry the same weight as a Cochrane Review aggregating 40,000 people across 80 trials. We note sample sizes in our citations and treat small studies as directional rather than definitive.
Does this finding apply to the specific demographic using this planner? A study conducted exclusively on one population group may not generalise. We flag these limitations explicitly rather than presenting universal claims from specific data.
A finding that confirms existing consensus is handled differently from one that changes it. When new evidence contradicts current guidance, we look for replication before updating — and we flag the uncertainty explicitly during the transition period.
The "Last Verified"
system.
Evidence changes. A meta-analysis published this month can overturn guidance that has held for a decade. Our content is not written once and left to age — every piece of THRESHOLD content carries a verification date, and that date is updated when new evidence is reviewed.
Every Knowledge Base article and Myth Registry page displays a "Last verified" date. This is the date when the content was last reviewed against current primary literature — not when it was published.
When significant new research changes our guidance, we update the relevant content and note what changed and why. We do not silently revise without explanation. If you read something in a THRESHOLD planner and come back six months later and the guidance has changed, there will be a note explaining the update and the source that prompted it.
This transparency is not a feature. It is the foundation of clinical trust. No other planner brand does this. We think it should be the standard.
The lines we
don't cross.
We are not a medical provider. Nothing in any THRESHOLD planner, Knowledge Base article, or Myth Registry page constitutes medical advice, diagnosis, or treatment. We present evidence — your provider interprets it for your specific situation.
We do not cite studies selectively to support a conclusion we've already reached. If the evidence is mixed, we say the evidence is mixed. If there is no reliable evidence on a topic, we say that rather than filling the gap with opinion dressed as fact.
We do not use validated clinical tools (PHQ-9, Edinburgh Postnatal Depression Scale, GAD-7) as diagnostic instruments. We use them as structured self-assessment frameworks to help people recognise patterns worth discussing with their provider. We make this distinction explicit wherever these tools appear.
We do not present wellness opinions, anecdotal claims, or motivational content as clinical evidence. If it does not have a citation, it does not appear in a THRESHOLD clinical tool.
The evidence, organised
by condition.
Everything in the Knowledge Base and Myth Registry follows this methodology. Every article. Every myth. Every claim.
