* Recognized risk factors for coronary heart disease, such as age, serum cholesterol
levels, body mass index, smoking history, diabetes and race, were not significant
in this model. � Of the 309 subjects for whom we had complete data, 156 did not have a diagnosis of coronary heart disease and 153 did, for a prevalence of 49.5 percent. � Of the 199 dentate subjects for whom we had complete data, 104 did not have a diagnosis of coronary heart disease and 95 did, for a prevalence of 47.7 percent. § Significant at P less than .05. ** NA: not applicable. The variable was omitted from the model. |
