Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case there are 100 comparisons, you can thus
expect the following amount of false-positive results:
  5.00 false positives, when considering a   5% risk acceptance (*, **, ***),
  1.00 false positives, when considering a   1% risk acceptance (**, ***),
  0.10 false positives, when considering a 0.1% risk acceptance (***)
