SCORING METHODOLOGY

How Chiron scores every article.

TRIAGE is the rubric behind every score in your digest — three independent domains instead of one misleading "importance" number, built specifically to answer the question a busy trainee actually has: is this worth reading fully, reading critically, or just skimming?

WHY NOT JUST ONE NUMBER

A single score hides more than it reveals.

A flawless, perfectly-run trial of a surrogate endpoint and a landmark trial that changes bedside practice can both look like "5 out of 5" under a single importance score — even though only one of them should actually change what you do tomorrow. TRIAGE keeps three separate questions separate, because they really are different questions:

E

Evidence Strength

How much can you trust the result? Starts from the study design itself, then adjusts for the specific limitations that actually weaken a finding.

I

Reporting Consistency

Does the paper's own conclusion actually match what it reported? Catches the gap between what a study found and what it claims to have found.

A

Clinical Applicability

Even a rock-solid finding may not apply to your patients. This domain asks whether the outcome studied is one that actually changes bedside care.

Each domain is scored independently from 0 to 5, in half-point increments. They're never averaged or summed — a weak score in any one domain matters on its own, which is exactly what determines your reading-priority tier.

READING-PRIORITY TIERS

The lowest domain governs the tier.

This is the rule that makes TRIAGE actually useful at a glance: your reading priority is set by whichever of the three domains is weakest, not by an average. A flawless trial measuring the wrong outcome still only earns a skim.

TierRuleSuggested Approach
Priority 1E, I, and A all ≥ 4Likely worth reading in full — probably practice-relevant.
Priority 2E, I, and A all ≥ 3Probably worth a critical read — check the methods before weighing it.
Priority 3Lowest domain = 2Likely a skim — useful context more than a reason to act.
Priority 4Any domain ≤ 1Probably awareness-only.
ExcludedI = 0Not shown in your digest at all — see below.

These are starting points for triage, not verdicts — every suggestion here can be, and sometimes should be, overridden by your own read of the abstract or paper.

That last row is a real, active safety behavior, not a theoretical one: if PubMed's own metadata indicates an article has been retracted, Chiron drops it from your digest entirely rather than showing it with a low score.

TWO SCORING MODES

Not every article gets read the same way.

A genuinely rigorous appraisal needs the full paper — funding disclosures, registration details, and a real look at study conduct all live in the full text, not the abstract. Chiron handles this honestly with two distinct modes, applied automatically depending on what's actually available.

Default — Every Article

TRIAGE-AE

The abstract-only edition. Every article is scored this way the moment it's fetched, using only the abstract and PubMed's own indexed metadata — nothing is guessed or inferred beyond what's actually stated.

  • Study design read from PubMed's own metadata, not inferred from prose
  • Every deduction traces to something the abstract explicitly says
  • No penalty for information an abstract simply wouldn't contain

If a full-text fetch or scoring attempt is unsuccessful for any reason, the article falls back to TRIAGE-AE automatically — you'll still get a properly scored article, it just won't carry the star.

WHAT IT LOOKS LIKE

The profile is always shown in full.

Per the rubric's own rule, Chiron never shows a tier by itself — the three domain scores are always displayed alongside it, right in the Chiron Analysis panel of every article:

Example

E 4 / I 5 / A 5 — Priority 1 ✦ Full Text Verified

In the digest itself, this appears as three compact rows of dots — one per domain — with the tier and star shown just beneath, in the same spot every article's score has always lived.

Not a validated instrument

TRIAGE is a tool Chiron built to help you triage a long list of articles, not a validated, peer-reviewed scoring system. It has not been tested against expert appraisal or outcomes research the way instruments like RoB 2 or GRADE have. Use it to help decide what to read first, never as a substitute for reading the article yourself or as the sole basis for a clinical or practice decision. A low score is a prompt to look closer if something seems off, not a verdict on the work — and a high score is not a guarantee of quality.

Working with less information than a full paper

TRIAGE-AE is a genuine, careful attempt to score what an abstract can honestly support — but it is still, unavoidably, working with less information than a full paper provides. Chiron is explicit about this rather than papering over it: the star is the signal that a score reflects real verification against the complete text, not just a confident-sounding estimate.
