Table 1.
Pairwise t‐tests performed between the microarray experiment treatment factors. Each of the 13 tests aids in the understanding of one of the four possible effects. Detailed results are shown in Table S1
| Effect | Factor 1 | Factor 2 | (Factor 1/Factor 2) estimated value is: |
|---|---|---|---|
| Transgene | OxO | AC | Overall effect of the transgene |
| OxO_H2O_pH 5.5 | AC_H2O_pH 5.5 | Effect of the transgene on water at physiological pH | |
| OxO_H2O_pH 2.4 | AC_H2O_pH 2.4 | Effect of the transgene on infiltration of acidic water | |
| OxO_OA_pH 2.4 | AC_OA_pH 2.4 | Effect of the transgene on infiltration of OA | |
| pH | H2O_pH 2.4 | H2O_pH 5.5 | Overall effect of the pH change 2.4 vs. 5.5 |
