Hello,
I am a beginner at using SAS University Edition and am unfamiliar with how to properly format my table in a way to meet the specific requirements of the "Binary Logistic Regression" function (i.e. number of events/trials).
I currently have variables set up for patient ID number as well as visit number. I do not believe that those are sufficient to use for this step. Any help is much appreciated.
Thanks

Your data needs to be set up as:
Events Trials <covariates>
If it's not set up this way, with one event per row then you can use the other type of specification.
<label:> MODEL variable <(variable_options)> = <effects> </ options>; <- Use this method;
<label:> MODEL events/trials = <effects> </ options>; <- don't use this method
The documentation has full exampls you can follow:

If you still have concerns, post an example of what your data looks like and explain specifically why you think it needs to be reformatted.
Here are instructions on how to provide sample data as a data step:
