Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case there are 8 comparisons, you can thus
expect the following amount of false-positive results:
0.40 false positives, when considering a 5% risk acceptance (*, **, ***),
0.08 false positives, when considering a 1% risk acceptance (**, ***),
0.01 false positives, when considering a 0.1% risk acceptance (***)
