Scientific safeguard

Qualified assessment is authoritative; chronology remains supporting evidence.

Praxis separates source-stated method or instrument changes from automated differences in CDC/NCHS method text. The qualified harmonization assessment below is the researcher-facing conclusion; method chronology explains the underlying evidence and does not override that adjudication.

Variable-by-variable chronology

Qualified harmonization assessment and indexed evidence

Each variable first shows the current qualified assessment used by Study Builder, followed by cycle-specific source evidence and method chronology.

Qualified Praxis harmonization assessment

Evidence developing · low confidence

No normalized longitudinal change evidence is available for this variable. Absence of events must not be interpreted as proof of cross-cycle equivalence.
