REDCap case file

Four site copies waited for an answer code none of them offered

All four branching rules wait for code 17, but none of the four answer lists includes it.

FormPath established this on translated dictionary logic, not by replaying a live REDCap project. The public source files are summarized here; they are not redistributed by FormPath.

Four site copies waited for an answer code none of them offered

All four branching rules wait for code 17, but none of the four answer lists includes it.

Impact
The “describe other ethnicity” question never appears. In the two copies with codes 0–6, that hidden field is also marked required.
How it was checked

TRANSLATED-MODEL PROOF

Why the branch failed

The branch expected a stored code no choice supplied.

Branching logic compares stored codes. In these four files, the “Other” labels map to 6 or 22 while the branch requires 17. The retained files establish that mismatch—not its history or cause.

  1. 1

    The branch expected 17

    Each affected follow-up used the same controlling rule: [ethnicity_1] = '17'.

  2. 2

    The supplied choices excluded 17

    Two offered codes 0–6 with “Other” stored as 6. Two offered 18–22 with “Other” stored as 22. None offered 17.

  3. 3

    No listed answer could open it

    On the supported translation, every possible value from the four dictionaries fails the rule. The two 0–6 copies also marked the hidden follow-up required.

Responsible publication

The finding is inspectable without republishing the instrument.

  • The rule, offered values, affected-file count, impact, and translated evidence boundary are retained as tested provenance.
  • Public definitions are summarized rather than distributed through this site.
  • The analyzer sample is explicitly synthetic and related only by defect shape.
