SYNTAX scores in patients with different Frank’s sign scores. The ear creases significantly associated with intermediate and high SYNTAX scores, as VC-EF and CC-NEH were used to calculated the Frank’s sign scores. Each ear crease of LVC-EF, RVC-EF, LCC-NEH, and RCC-NEH was scored as 1 point, then the patients could have 0–4 points according to the ear creases, with the total score constituting the Frank’s sign score.
