* CHD: coronary heart disease; PBS: papillary bleeding score.

� Of the 195 subjects for whom we had complete data, 113 did not have a diagnosis of CHD and 82 did, for a prevalence of 42 percent.

� Of the 147 subjects for whom we had complete data, 86 did not have a diagnosis of CHD and 61 did, for a prevalence of 41 percent.

§ Of the 114 subjects for whom we had complete data, 71 had a diagnosis of CHD and 45 did not, for a prevalence of 62 percent.

** Of the 52 subjects for whom we had complete data, 34 had a diagnosis of CHD and 18 did not, for a prevalence of 65 percent.
