Description
Choose a supplied withdrawal date or a display mask.
Developmental records distinguish calendar age, supplied age corrections, observation states, assent and privacy choices. A corrected age can be negative under supplied assumptions, and a missing response differs from an observed zero. A display mask changes presentation without protecting the underlying record.
Choose a supplied withdrawal date or a display mask.
When to use this tool
Use Developmental Study Withdrawal Date Mask when you already have withdrawalDate, discloseDate, suppliedMask and need to choose a supplied withdrawal date or a display mask.
How to use the tool and how it works
- Enter withdrawalDate, discloseDate, suppliedMask. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read displayText. Use the output convention below.
Require a real UTC withdrawalDate even when discloseDate=false; return date if true, otherwise suppliedMask.1

}Limitations and assumptions
- A mask may be empty and changes display only. It does not remove underlying data, establish anonymity, verify withdrawal or authorize disclosure.
- 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.
Alternative or Complementary methods
Use the complete observation or assessment method, age convention and consent context. Review source records and data protection together; local counts, labels and geometric measurements do not establish development, diagnosis or appropriate support.
