The 3 groups were superimposable for gender (P = .086), fT4 (P = .899), fT3 (P = .434), TRAb titers (P = .882), and thyroid volume (P = .840) at disease onset. Isolated GD patients exhibited Graves orbitopathy more frequently (P &amp;lt; .001), a higher rate of definitive therapy (P &amp;lt; .001) and shorter time between disease onset and definitive therapy (P &amp;lt; .001) compared to the GD1-APS and GD2-APS patients.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n
