Create footnotes for individual p-values

The usual presentation of footnotes for p-values on a gtsummary table is to have a single footnote that lists all statistical tests that were used to compute p-values on a given table. The separate_p_footnotes() function separates aggregated p-value footnotes to individual footnotes that denote the specific test used for each of the p-values.

Usage

separate_p_footnotes(x)

Arguments
