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.

These next questions are about pain in the back, neck or hip area that {you/SP} may have had. Please look at this hand card. HAND CARD ARQ1 {Have you/Has SP} ever had pain, aching or stiffness in any of these locations almost every day for at least 6 weeks in a row? Include pain even if it was mild.
