Details

Multiple choice variables exist in REDCap data as a set of 0/1/TRUE/FALSE variables, where 1/TRUE represents a selected/checked answer. Hence, for a single multiple choice 'question' in the datadictionary/metadata with n options, there are n variables. Each variable is the variable name (e.g. morbidities) followed by 3 underscores (___) and the option number (e.g. 1) - morbidities___1.
