I am running a stratified analysis in epi.2by2. I need help in understanding why the cohort.count option works but the case.control does not (as shown below). Any help is greatly appreciated!
compute odds ratio adjusted for sex
alltable < table(prob1$coffeedrinker, prob1$case, prob1$sex, dnn = c("Coffee", "Case", "Sex"))
alltable
, , Sex = 1
Case
Coffee 1 0
1 140 280
0 11 56
, , Sex = 0
Case
Coffee 1 0
1 207 275
0 9 32
adjtable < epi.2by2(alltable, method = "cohort.count", digits = 2, conf.level = 0.95, units = 100,

interpret = FALSE, outcome = "as.columns")
print(adjtable)
