Correlations between length of incision (LI)/thyroid volume and length of incision/neck circumference.This figure shows the correlations between length of incision (cm.)/thyroid volume (ml.) in diamonds and bold line and length of incision (cm.)/neck circumference (cm.) in squares and dotted line. Thyroid volume explains 44 % of variance in LI, while neck circumference almost 30 %.
