Ratio = Multiplicative increase in MetS rate between any two successive visits (bold indicates different than 1 (p < 0.05))

^**

Difference = Additive increase in mean MetS severity between any two visits (bold indicates different than 0 (p < 0.05))

Statistical comparisons (white male as referent):

Different than white male (p < 0.05)

Different than white female (p < 0.05)

Different than African-American male (p < 0.05)
