Multivariable OR: adjusted further for age and sex, systolic blood pressure, body mass index, smoking status, alcohol intake, serum triglycerides, serum HDL-cholesterol, and HbA1c. Handgrip strength levels tertiles: <25.5 kg, 25.5-35.0 kg, and >35.0kg for men and <18.5kg, 18.5-22.0kg, and >22.0kg for women. Lower platelets are defined as < 21.6×104 /μL for men and < 22.6×104 /μL for women. Carotid atherosclerosis is defined as a carotid intima-media thickness ≥1.1mm. SD: standard deviation. 1 SD increment in handgrips strength are 9.4kg for men and 5.0kg for women.
