Description
Compare arm contact times after optional common-time removal.
Health-research records connect study identifiers, source assertions, outcome labels and timing conventions. A coverage count, literal match or recorded interval can expose missing information, while the quality of evidence, actual blinding and treatment effectiveness still require assessment of the original study.
Compare arm contact times after optional common-time removal.
When to use this tool
Use Study Arm Contact Base Gap when checking a supplied study-record, evidence-support or timing convention.
How to use the tool and how it works
- Enter firstContactMinutes, secondContactMinutes, commonAdministrativeMinutes, removeCommon. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read firstAdjusted, secondAdjusted, gap. Use the output convention below.
Compare arm contact times after optional common-time removal. Require nonnegative contact times and commonAdministrativeMinutes <= both; adjusted times subtract common when removeCommon, gap remains first-second.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstContactMinutes | First Contact Minutes | Required. Finite number; minimum 0. |
| secondContactMinutes | Second Contact Minutes | Required. Finite number; minimum 0. |
| commonAdministrativeMinutes | Common Administrative Minutes | Required. Finite number; minimum 0. |
| removeCommon | Remove Common | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| firstAdjusted | First Adjusted | Required. Finite number. |
| secondAdjusted | Second Adjusted | Required. Finite number. |
| gap | Signed difference under the stated comparison convention, with matching units. | Required. Finite number. |

}Limitations and assumptions
- Common removal leaves this difference invariant; actual comparator equivalence or treatment-contact matching is 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
Read the original research and registration records, appraise study design and bias, and consult qualified health professionals for conclusions that affect care.
