Blóðþrýstingur var marktækt hækkaður (p<0,05) í körlum yngri en 60 ára, sem höfðu hægra greinrof, miðað við samanburðarhóp. Marktæk fylgni var við hjartastækkun (p<0,05) og hækkaðan fastandi blóðsykur (p=0,05) í sama hópi. í sama aldurshópi kvenna með hægra greinrof var einnig fylgni við háþrýsting (p<0,05). Samanburður á tíðni ýmissa breyta milli hægra greinrofshóps og samanburðarhóps er birtur í töflum III og IV. Marktækur munur reyndist á dánartíðni karla með hægra greinrof úr hjartasjúkdómum (p<0,01) miðað við samanburðarhóp. Þegar leiðrétt var fyrir aldri og fleiri breytum með
