No blocking method discontinuity is identified inside the selected cycle span, but one or more longitudinal changes require explicit harmonization conditions before pooling.
Evidence provenance: Praxis automated inference from indexed CDC/NCHS evidence
Evidence signals: source-derived
Relevant boundaries: 1999-2000 → 2001-2002 · 2001-2002 → 2003-2004
Praxis harmonization actions
- Apply cycle-specific eligibility rules and restrict the pooled analytic population to a defensible common target population.
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.

Praxis harmonization actions
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.
- Select the weight appropriate to each cycle and subsample; when pooling cycles, construct the combined weight according to NHANES guidance rather than reusing a single-cycle weight unchanged.
- Apply cycle-specific eligibility rules and restrict the pooled analytic population to a defensible common target population.
- Confirm that the construct and coding are unchanged before pooling or recoding.
