  1. Prevalence of elevated biomarker ratios, including socio-demographic, health, and behavioral characteristics compared between adults with versus without MetS using t-tests and chi-squared analysis, as appropriate. All P < .01; chi-square for frequencies, and independent sample t-test for continuous measures. Values in parentheses represent SEM for continuous measures or SE for proportions
