Description
Check an outcome time against explicitly open or closed endpoints.
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.
Check an outcome time against explicitly open or closed endpoints.
When to use this tool
Use Trial Outcome Window Closure Token when checking the stated clinical-research record, allocation, timing, analysis or evidence-basis convention.
How to use the tool and how it works
- Enter time, start, end, closedStart, closedEnd. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inside. Inspect inside before interpreting the associated values.
Check an outcome time against explicitly open or closed endpoints. Require start <= end; inside uses closedStart and closedEnd to choose inclusive or strict comparisons independently.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| time | Time | Required. Finite number. |
| start | Start | Required. Finite number. |
| end | End | Required. Finite number. |
| closedStart | Closed Start | Required. Boolean. |
| closedEnd | Closed End | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| inside | Inside | Required. Boolean. |

}Limitations and assumptions
- A coincident interval contains its point only with both ends closed; actual outcome eligibility and protocol interpretation are not established.
- 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.
