Again, there was an expected treatment-by-time interaction (F(1,20)=73.105, P< .001): the plasma ratio increased 17.2% from T0 to T5 following TRP+, which showed a trend towards significance (mean T0=0.156, SD=0.046, mean T5=0.189, SD=.015, t(21)=1.931, P =.067), and significantly decreased 85.1% from T0 to T5 following TRP- (mean T0=0.166, SD=0.054, mean T5=0.025, SD=0.012, t(21)=13.860, P< .001).
