matched_or {catfun} | R Documentation |
Create odds ratio and confidence interval from matched pairs data.
matched_or(df, ...)
df |
a dataframe with binary variables x and y or a 2 x 2 frequency table/matrix. If a table or matrix, x and y must be NULL. Used to select method. |

further arguments passed to or from other methods. |
The matched pairs odds ratio and confidence interval is the equivalent of calculating a Cochran-Mantel-Haenszel odds ratio where each pair is treated as a stratum.
a list with class "matched_or" with the following components:
tab |
2x2 table using for calculating risk difference |
or |
dataframe with columns corresponding to matched-pairs OR, lower bound, and upper bound of CI |
conf.level |
specified confidence level |
