Enrolled subjects underwent ultrasonographic studies of the neck between 2009 and 2018.

Screening revealed TNs in 500 screenees (42.5%; confidence interval [CI] 39.7\u201345.4%). Ninety-seven of these (19.4%; CI 16.2\u201323.1%) underwent FNAB. Only 11 cases of TC were diagnosed in the whole population (0.9%; CI 0.5\u20131.7%). The prevalence of TC in screenees from kindreds with \u22653 cases (3\/24, 12.5%) was higher than that for kindreds with one affected member (6\/346, 1.7%;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.01, odds ratio [OR] 7.99; CI 1.21\u201340.75) and for those with two affected members (2\/103, 1.9%;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.05, OR 7.05; CI 0.76\u201389.44).

warranted in kindreds with this level of familiality.<\/jats:p>\n
