Wrapper for _CI_2x2 functions on Chapter 4.
the_2x2_table_CIs_ratio(n, alpha = 0.05)NULL. This function should be called for its printed output
In most study designs, rows designate a grouping of the data, for instance, into treatment or exposure groups, while the columns indicate a dichotomous outcome, usually with the first column representing the outcome of interest. This designation of rows and columns may not be relevant in all study designs, please see the introduction to chapter 4 for details.
