Alpha level = 0.05; Bonferroni-adjusted = 0.05/21 = 0.024. After application of the corrected p-level, the significant effect (with unadjusted level, highlighted in bold in Table 2) would not remain. The likelihood of by chance detecting a significant result is 5%, with 21 tests this equals 1.05 tests that would be detected as significant by pure chance.
