  1. *Confidence levels, 95% upper and lower confidence intervals (brackets) and the p value are listed for each set of independent and dependent variables tested in the regression model using weighted values. Significant values (p < 0.05) are highlighted
  2. *Ethnicity = white is the reference group; the omnibus test of ethnicity is statistically significant for WBC, Lymph, Neutro and Mono
