*p Values for trend obtained by including categories as an ordinal covariate in regression equations. †Because of differences in the distribution of income in white and black people, the two lower categories are combined in white subjects and the two highest categories are combined in black subjects. ‡Corresponds to average change per unit difference in category. Obtained by including income and education categories in regression equations as ordinal covariates.
