The Medication Use Questionnaire (MUQ) was administered in 2013 in participants in both arms of the trial. Data includes aspirin, acetaminophen, and NSAID usage, prescription drug usage, weight and BMI, and smoking status. To learn more about the Medication Use Questionnaire (MUQ) data collected as part of the study, visit the PLCO Medication Use (MUQ) documentation page.

For each dataset, a Data Dictionary that describes the data is publicly available. In order to obtain the actual data in SAS or CSV format, you must begin a data-only request. Data will be delivered once the project is approved and data transfer agreements are completed.
