- none opened · not found: The WHO diabetes fact sheet (dated 11 November 2026) states no numeric thresholds; the WHO 2006/2011 reports were not opened. No independent second source was opened.
- Contested
- no: ADA thresholds match long-standing WHO thresholds for A1C and FPG, but WHO's current text was not opened; the A1C criterion is less sensitive in some populations (ADA text).
