Description
Return claim-to-citation publication-year age.
Health-research records connect study identifiers, source assertions, outcome labels and timing conventions. A coverage count, literal match or recorded interval can expose missing information, while the quality of evidence, actual blinding and treatment effectiveness still require assessment of the original study.
Return claim-to-citation publication-year age.
When to use this tool
Use Study Claim Citation Age when checking a supplied study-record, evidence-support or timing convention.
How to use the tool and how it works
- Enter claimYear, citedPublicationYear. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read citationAgeYears, futureCitation. Inspect futureCitation before interpreting the associated values.
Return claim-to-citation publication-year age. citationAgeYears = claimYear-citedPublicationYear, futureCitation means the publication year is later.1

}Limitations and assumptions
- Dates and citation identity are supplied; age alone does not establish valid support, currency or evidence quality.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Read the original research and registration records, appraise study design and bias, and consult qualified health professionals for conclusions that affect care.
