In this paper, the authors compiled individual participant data from 25 cohort studies that included a sample of about 80,000 subjects followed for a period of 6.8 years. This study, also called the Asia Pacific Cohort Studies Collaboration (APCSC), includes individual studies from Asia and Australia. The authors concluded that HDL cholesterol is related to risk of coronary heart disease (CHD) in the Asian Pacific population and that a lower cholesterol/HDL cholesterol ratio is associated with a reduced risk of CHD.
