Description
Compute offset=definitionYear-referenceYear using exact integer subtraction before conversion to the numeric output.
Evidence review distinguishes reporting completeness, source identity, timing, comparator descriptions, and the validity of a clinical claim. Matching metadata or calculating an interval cannot establish study quality or treatment efficacy. Measurement and protocol conventions need to remain explicit before records are compared.
Compute offset=definitionYear-referenceYear using exact integer subtraction before conversion to the numeric output.
When to use this tool
Use Public Definition Source Year Offset when you need this specific evidence-record, measurement, interval, comparator, or protocol check.
How to use the tool and how it works
- Enter definitionYear, referenceYear. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read offset. Use the output convention below.
Compute offset=definitionYear-referenceYear using exact integer subtraction before conversion to the numeric output.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| definitionYear | Definition Year | Required. Safe integer. |
| referenceYear | Reference Year | Required. Safe integer. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| offset | Signed coordinate or time offset under the stated formula. | Required. Safe integer. |

}Limitations and assumptions
- Years are supplied integer labels. A publication-year offset does not establish a definition's authenticity, current status, evidentiary support, or clinical validity; out-of-range numeric output is rejected.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use a substantive source and study appraisal for clinical claims. Verify methods, preregistration, reporting, comparator conditions, and measurement validity beyond matching labels or calculated completeness.
