a Table values are mean ± SD for continuous variables and n (column %) for categorical variables
b Characteristics included are covariates in at least one ethnic-specific linear regression model
c Sample size represents number of individuals that passed quality control and have complete data for all ethnic-specific linear regression model covariates
d Percentages may not sum to 100 % due to rounding and n’s may not sum to sample size due to missing values for variables not included as covariates in ethnic-specific regression models
