Adjustment required · high confidence

A methodological discontinuity falls inside the selected cycle span. Naive pooling of raw values across the flagged boundary is not recommended unless CDC/NCHS provides a defensible calibration or comparability procedure.

Evidence provenance: Praxis automated inference from indexed CDC/NCHS evidence

Relevant boundaries: 1999-2000 → 2001-2002 · 2001-2002 → 2003-2004 · 2003-2004 → 2005-2006 · 2005-2006 → 2007-2008 · 2007-2008 → 2009-2010 · 2009-2010 → 2011-2012 · 2011-2012 → 2013-2014 · 2013-2014 → 2015-2016 · 2015-2016 → 2017-2018 · 2017-2018 → 2017-2020 · 2017-2020 → 2021-2023

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.
Review the adjacent codebooks/methods. Keep this boundary as documentation variation unless source evidence confirms a substantive method or instrument change.
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 CDC/NCHS comparability or calibration guidance where available. If equivalence is not established, preserve separate method periods or perform sensitivity analyses rather than naively pooling raw values.
Confirm that the construct and coding are unchanged before pooling or recoding.
