WebApr 23, 2024 · You do a Fisher's exact test on each of the 6 possible pairwise comparisons (daily vs. weekly, daily vs. monthly, etc.), then apply the Bonferroni correction for multiple tests. With 6 pairwise comparisons, the P value must be less than 0.05 / 6, or 0.008, to be significant at the P < 0.05 level.

WebSep 28, 2024 · Short answer: A 2 × 2 table has 1 degree of freedom (df), and one odds ratio (OR) correspondingly. A 2 × 3 table has two df, and two ORs. In that case, the null hypothesis tested by Fisher's test can be formulated as both the ORs being equal to 1. You could calculate the ORs by splitting into two 2 × 2 tables, or simply by using a logistic ... WebThe formula can also be presented as (a × d)/ (b × c) (this is called the cross-product). The result is the same: (17 × 248) = (15656/4216) = 3.71. The result of an odds ratio is interpreted as follows: The patients who received standard care died 3.71 times more often than patients treated with the new drug.
