Criteria-era drift makes old and new EDS literature non-equivalent

findingevidence: established

Villefranche-era “EDS type III” cohorts (1997–2017) do not map cleanly onto 2017 hEDS. The 2017 criteria are stricter, and some people who met the older hypermobility-type criteria would now be diagnosed with HSD. Studies that mix eras need to be read with that in mind.
