Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case there are 29 comparisons, you can thus
expect the following amount of false-positive results:
 1.45 false positives, when considering a   5% risk acceptance (*, **, ***),
 0.29 false positives, when considering a   1% risk acceptance (**, ***),
 0.03 false positives, when considering a 0.1% risk acceptance (***)
