Please do we use this only if the data is normally distributed? I ask so because i am not sure when to use the 95% confidence interval or the p value

[@pk11kent]

Very good question - the data themselves are discrete, so cannot be normal distributed. However, the log odds ratios are roughly normal distributed, hence you can calculate the 95% confidence interval of the log odds ratio. Note - the odds ratio is NOT normal distributed - that’s why you have to do the log-transformation.
