We have denoted CI and PP values that are significantly different than the PN values with 1 for p≤0.01 and 2 for p≤0.05 and CI values that are significantly different than PP values with 3 for p≤0.01 using paired t-tests.

For F-tests all significant results are show with p<0.01 and NS stands for not significant.
