Description
Return corrected recorded age and offset from a target.
Chronological, corrected and age-equivalent values use different anchors and assumptions. Arithmetic can compare supplied age coordinates, but a clinical correction or interpretation of developmental delay is not determined by subtraction alone.
Return corrected recorded age and offset from a target.
When to use this tool
Use Participant Age Correction Offset when checking a supplied research age anchor or offset.
How to use the tool and how it works
- Enter recordedAgeDays, suppliedCorrectionDays, targetAgeDays. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read correctedAgeDays, targetOffsetDays. Use the output convention below.
Return corrected recorded age and offset from a target. correctedAgeDays = recordedAgeDays+suppliedCorrectionDays; targetOffsetDays subtracts targetAgeDays.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordedAgeDays | Recorded Age Days | Required. Safe integer. |
| suppliedCorrectionDays | Supplied Correction Days | Required. Safe integer. |
| targetAgeDays | Target Age Days | Required. Safe integer. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| correctedAgeDays | Corrected Age Days | Required. Safe integer. |
| targetOffsetDays | Target Offset Days | Required. Safe integer. |

}Limitations and assumptions
- Correction is added and may produce negative age; no clinical age-correction convention is selected.
- 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 appropriate professional guidance and validated assessment before interpreting corrected or age-equivalent values for an individual.
