Biomarkers with P<0.05 displayed.
For each biomarker (dependent variable), we exponentiated the adjusted mean log-transformed biomarker and its 95% confidence interval to obtain its adjusted geometric mean and corresponding 95% confidence interval. Covariates in multivariable model include covariates listed in Table 3 legend.
