matched_or: Matched pairs odds ratio and confidence interval

Description

Create odds ratio and confidence interval from matched pairs data.

Usage

matched_or(df, ...)

Arguments

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.

Value

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

Details

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.

Examples

# NOT RUN {
set.seed(1)
gene <- data.frame(pair = seq(1:35),
                   ulcer = rbinom(35, 1, .7),
                   healthy = rbinom(35, 1, .4))

matched_or(gene, ulcer, healthy)
# }
