Treatment Control Level
Specify a control (reference) level of the treatment arm . The level that you specify is used as the reference against other levels of the Treatment Variable in the Cochran-Mantel-Haenszel exact test to screen events or interventions for difference in incidence.
Note : If you leave this field blank , the default level is “Placebo” or “Pbo” (both case insensitive) if found. Otherwise, it is the first sorted level.
To Specify a Treatment Control Level:
Enter one level of the Treatment Variable enclosed in double quotation marks ( “” ).
