  1. 1 The rye and wheat indices were calculated as follows: Relative change xijk = (Peak area xijk at 30 min - Peak area xijk at baseline)/(median of peak areas xijk) where xij is the metabolite i measured for each subject j (j = 1-16) and bread k (k = 1 (rye bread), 2 (wheat bread). 2 Paired samples t-test. 3 q-values were calculated from p-value distribution obtained from paired samples t-test.
