For these studies, subsets of PLCO participants of interest were selected and additional data were ascertained through extra surveys, questionnaires, research and testing. Studies include a collaboration with a manufacturer regarding a free PSA assay, study center collaborations on cost-effectiveness and quality of life assessments, and a study of colonoscopy utilization. </p> <p> For each dataset, a Data Dictionary that describes the data is publicly available.
