yamaa As a clinical trial statistician or programmer, challenge anything in this benchmark: describe a problem in Comments, or propose a fix with the Edit button on any source file.
- Task: Would a real study need this derivation, specified this way? Does it follow CDISC standards: variable names, controlled terms, record structure? Flag any rule that is ambiguous or that a sponsor would handle differently.
- Inputs: Do they look like data collected in a real trial, and do they include the situations you would expect to meet in one?
- Expected output: Would independent QC programming reproduce every value from these inputs and rules?
The other tabs beside Comments are background for assessment, not under review.
Summary
EditUnder reviewWhat this benchmark meansREADME.mdGoal: pin how a dictionary lookup tells a missing code from a collected code outside the dictionary.
Input: spec.yaml decodes coded sex from DM twice: once with a
separate named result for codes outside the dictionary, once with one named
result for both events. DM carries listed codes, a missing code, and a
code outside the dictionary.
Note: a missing code means "not collected"; a collected code outside the
dictionary means "outside the codelist" and is usually a data-quality
finding. The SEXC column keeps the missing code missing and reads the
outside code as Outside codelist. The SEXC_SINGLE column names the same
result, Unknown, for both events.
