Description
Return age remaining to a supplied assent-renewal anchor.
Participant time, compensation and renewal timing depend on explicit assumptions about visits, expenses, comprehension and applicable rules. A supplied rate or elapsed-time threshold can support bookkeeping while fair compensation, accessibility and valid consent require a broader contextual assessment.
Return age remaining to a supplied assent-renewal anchor.
When to use this tool
Use Assent Renewal Age Anchor Offset when checking the stated research payment, burden, reading-time or renewal convention.
How to use the tool and how it works
- Enter currentAge, suppliedRenewalAge. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read ageRemaining, reached. Inspect reached before interpreting the associated values.
Return age remaining to a supplied assent-renewal anchor. Require nonnegative currentAge/renewalAge; ageRemaining = renewal-current, reached uses >=.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| currentAge | Current Age | Required. Finite number; minimum 0. |
| suppliedRenewalAge | Supplied Renewal Age | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| ageRemaining | Age Remaining | Required. Finite number. |
| reached | Reached | Required. Boolean. |

}Limitations and assumptions
- The anchor is supplied; actual capacity, appropriate assent renewal and legal age requirements are not determined.
- 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 participant-centered evidence and the original protocol and consent process; review payment, accessibility and renewal choices with the responsible ethics and professional teams.
