Treatment Summary: | As part of the parent study, daidzein, equol, and ODMA concentrations were analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS) as detailed elsewhere (Franke et al 2009). These previously measured concentrations were used to classify metabotypes. Each urine sample was identified as being ODMA producer/non-producer and equol producer/non-producer based on a cut-off of equol/ODMA:daidzein ratio of 0.018 (36). All samples, except two samples, which were excluded from selection, had daidzein concentrations >2 nmol/mg creatinine, indicating sufficient presence of the precursor metabolite for metabolite detection. |
