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 · automated-difference
Relevant boundaries: 2007-2008 → 2009-2010 · 2009-2010 → 2011-2012 · 2011-2012 → 2013-2014 · 2013-2014 → 2015-2016 · 2015-2016 → 2017-2018
Praxis harmonization actions
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.
- Confirm that the construct and coding are unchanged before pooling or recoding.

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.
