a: Spearman's coefficient of rank correlation with lectin staining-intensity score.

b: Chi-square statistic and P value, Mantel-Haenszel (MH) test for correlation between ordinal categorical variables. P values shown in bold face are statistically significant at 0.5% alpha.

c: Number non-missing. Total is total non-missing; AA is non-missing African-Americans.

d: P value for rank correlation of Age (continuous variable) with lectin staining-intensity score.
