The CaWY study is a cross-sectional, multicenter, population-based sonographic survey with blinded central image adjudication, reported in accordance with STROBE guidelines for cross-sectional studies, aimed at estimating the prevalence of CaW detected by duplex sonography in the general population aged 15-25 years.",[72],"Carotid Web",[74,75,76,77],"Prevalence","Carotid artery","Carotid web","Duplex sonography","2026-03-22",{"date":80,"type":81},"2026-03-27","ACTUAL",{"date":83,"type":81},"2026-01-04",{"date":85,"type":68},"2027-02-28",{"name":5,"class":6},1]
