Rank product (RP ^1/20 ) from multilevel partial least-squares discriminant analysis models of the comparsion between the NMR spectra of serum after the intake of refined wheat bread vs the intake of whole grain rye bread in postmeopuasal women (n=33). 1: Isoleusine; 2: Leusine; 3: N,N-dimethylglycine; 4: Betaine; 5: an overlapping signal with glucose at 3.875 ppm; 6: small signal in an overlapping area at 3.965 ppm. Chemical shift indicates the chemical shift of the spectral buckets used for multivariate analysis.
