Hypertension	38.59 (−46.24 to 123.43)	0.37	84.52 (−18.77 to 187.81)	0.11
Diabetes	−11.30 (−100.94 to 78.35)	0.80	13.46 (−91.49 to 118.40)	0.80

LDL	−0.62 (−2.15 to 0.92)	0.43	−0.18 (−1.99 to 1.62)	0.84
CHO	14.00 (−25.25 to 53.24)	0.48	−23.11 (−64.86 to 18.63)	0.27
ICAA (deg.)	1.16 (−2.56 to 4.88)	0.54	−0.70 (−5.16 to 3.77)	0.76
BIFA (deg.)	−0.62 (−3.59 to 2.35)	0.68	−0.05 (−4.01 to 3.90)	0.98

Adjusted for sex, age, hypertension, diabetes, smoking, LDL, ICAA, BIFA, and nonplanar ICAA.

BIFA indicates bifurcation angle; CHO, cholesterol; CI, confidence interval; ICAA, internal carotid artery angle; LDL, low-density lipoprotein.
