To test differences (diffGOI) in the expression rate between the treatments
and to obtain fold change (FC) values from the estimated TG differences,
the approach suggested in Steibel et al. (2009) was used. The
significance of the diffGOI estimates was determined with the t statistic.
Additionally, asymmetric 95% confidence intervals (up and low)
were calculated for each FC value using the standard error (SE) of
diffGOI:
