Nishimura et al reported scores for predicting the risk of coronary heart disease in an urban Japanese population. One score is based on serum LDL concentration while a second uses serum total cholesterol. The authors are from National Cerebral and Cardiovascular Center in Osaka, Keio University, Hyogo College of Medicine, and Japan Anti-Tuberculosis Association in Tokyo.
The Suita Study is similar to the Framingham studies based on urban residents living in Suita, part of Osaka, Japan.
