Key inclusion criteria
This cross-sectional study focused on the primary prevention of ASCVD, examining the relationship between fish consumption, lifestyle, TSB, and inflammation. Among 11,678 Japanese individuals over 20 years who underwent annual health checkups between April 2019 and March 2020 at the Health Planning Center of Nihon University Hospital.
Key exclusion criteria
unwillingness to provide informed consent for participation, positive history of ASCVD, C-reactive protein (CRP)levels more than 2.0 mg/dL, the presence of hepatitis B virus surface antigen, hepatitis C antibodies, hepatic cirrhosis, hepatocellular carcinoma, and metastatic liver cancer or no measurement of leukocyte and leucocyte subclass count, CRP levels, and TSB levels. We also excluded participants with TSB levels of more than 2.0 mg/dL to exclude constitutional jaundice as much as possible.
