I am writing a meta-analysis on the complication and reoperation rates after 5 treatment modalities of distal radius fractures. Currently I am doing a post hoc analysis on the differences of 7 types of complications between the 5 treatment modalities seperately(4 comparisons, 4 of the treatments compared to the gold standard). I want to use the conservative Bonferroni correction for the alpha and read the other articles on multiple comparisons and the bonferroni correction. I am just not sure what number to divide the alpha by. Should I divide the alpha(which I set at 0.05) by 4 because of the 4 comparisons or not?
