www.cms.gov: technology ↔ issues

Accessibility findings that appear disproportionately on pages running a given technology, across the 277 page(s) in 2026-W37 where both technology detection and an accessibility engine ran. Lift is how many times more likely a finding is on pages with the technology than on pages overall — a value of 2× means twice the baseline rate.

This is an association, not proof of cause. Technologies that are detected on the same set of pages (e.g. a CMS, its host, and its language) will share identical lift values; the listing groups by technology but cannot tell which one in a co-located stack is responsible. Treat high-lift pairs as leads for a human to confirm — a barrier that recurs with the same technology, especially across multiple sites, is likely a bug in that technology rather than in any one page's content.
