Figure 4

Scatterplots with regression lines for selected m/z features associated with hepatic fat fraction in integrative network analysis and multiple linear regression. The x-axis is square root-transformed hepatic fat fraction, and the y-axis is log-transformed ion abundance of each m/z feature. All m/z features shown were annotated or identified at level 2 or level 1, respectively, based on the Metabolomics Standards Initiative criteria, to the adduct listed in parentheses. Reported β-coefficients and their p values were calculated using multivariable linear regression of hepatic fat fraction with each m/z feature adjusted for age, sex, race/ethnicity, body mass index z-score, and abdominal fats. m/z, mass to charge ratio.
