Coefficients of metabolites contributing to separation between control and alcohol treated animals in spectra of urine and liver extract. The sign indicates the direction of change as compared to controls. The values in parenthesis are the cross validated standard errors for each coefficient and confirms the statistical significance of the values.

^{a & b}

The peaks for isoleucine, leucine and valine peaks fall within the same bin as do the peaks for maltose and glucose. These metabolites have the same coefficient values.
