Description
Return query-open durations across supplied reopen episodes.
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 query-open durations across supplied reopen episodes.
When to use this tool
Use Trial Data Query Repeat Open Duration when checking the stated clinical-research record, allocation, timing, analysis or evidence-basis convention.
How to use the tool and how it works
- Enter openTimes, closeTimes, now. 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 closedDuration, openDuration, episodes. Use the output convention below.
Return query-open durations across supplied reopen episodes. Require alternating ordered open/close arrays with at most one unmatched opening, all times <= now; closedDuration sums closed spans, openDuration is current unmatched span, episodes = opens.length.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| openTimes | Open Times | Required. Array of finite number; maximum items 256. |
| closeTimes | Close Times | Required. Array of finite number; maximum items 256. |
| now | Now | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| closedDuration | Closed Duration | Required. Finite number. |
| openDuration | Open Duration | Required. Finite number. |
| episodes | Episodes | Required. Safe integer. |

}Limitations and assumptions
- Events are supplied and may touch; no actual query state, resolution quality or regulatory timeliness is verified.
- 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.
