Description
Return supported analysis-window duration.
Clinical research distinguishes supplied protocol metadata, participant/event records, allocation bookkeeping and an analysis target. A local count, permission flag or denominator choice can help reconcile records without establishing valid consent, randomization, regulatory compliance or a reliable treatment-effect estimate.
Return supported analysis-window duration.
When to use this tool
Use Analysis Window Support Share when checking the stated clinical-research record, allocation, timing, analysis or evidence-basis convention.
How to use the tool and how it works
- Enter durations, inAnalysisWindow, outcomeKnown, covariatesKnown. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read analysisDuration, supportedDuration, share, defined. Inspect defined before interpreting the associated values.
Return supported analysis-window duration. Require aligned nonnegative durations and window/outcome/covariate flags; analysisDuration sums in-window time, supportedDuration also requires both known flags; divide or return zero with defined false.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| durations | Durations | Required. Array of finite number; minimum 0; maximum items 256. |
| inAnalysisWindow | In Analysis Window | Required. Array of boolean; maximum items 256. |
| outcomeKnown | Outcome Known | Required. Array of boolean; maximum items 256. |
| covariatesKnown | Covariates Known | Required. Array of boolean; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| analysisDuration | Analysis Duration | Required. Finite number. |
| supportedDuration | Supported Duration | Required. Finite number. |
| share | Dimensionless numerator/denominator ratio under the explicit basis above. | Required. Finite number. |
| defined | Whether the stated denominator or information basis permits interpretation of the associated value; inspect before using a placeholder. | Required. Boolean. |

}Limitations and assumptions
- No interval overlap removal, data authentication or missing-data bias assessment is performed.
- 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
Use the complete approved protocol, authenticated source records and qualified clinical/statistical oversight for actual trial design, conduct and interpretation.
