Description
Return a supplied research-item contribution under explicit inclusion and weight flags without a validated score.
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.
Return a supplied research-item contribution under explicit inclusion and weight flags without a validated score.
When to use this tool
Use Questionnaire Item Domain Weight when you need this specific evidence-record, measurement, interval, comparator, or protocol check.
How to use the tool and how it works
- Enter value, suppliedWeight, included. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read contribution. Use the output convention below.
For nonnegative suppliedWeight return contribution=value*weight if included, otherwise zero.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| value | Value | Required. Finite number. |
| suppliedWeight | Supplied Weight | Required. Finite number; minimum 0. |
| included | Included | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| contribution | Contribution | Required. Finite number. |

}Limitations and assumptions
- Value may be signed and no scale bounds or weight normalization are imposed. This is one supplied questionnaire term, not a validated score, latent construct, or clinical outcome.
- 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.
