Follow-up and analysis has continued on the 361,662 men screened and the 12,866 men randomized.\n\nDESIGN NARRATIVE:\n\nThe National Death Index (NDI) will be used for continued follow-up of the MRFIT cohorts. An additional assay to establish IGF-1 and IGF binding protein will be added to the data set as a potential prognostic factor. The effort will focus on three primary aims related to long-term mortality. Aim 1 will relate nutritional-dietary data to twenty-five year mortality from coronary heart disease (CHD), stroke, cardiovascular disease (CVD), colon cancer, prostate cancer, and all causes for the 12,866 men randomized. Aim 2 will relate age, ethnicity, socioeconomic position, geographic location, major risk factors, low risk status, prior diabetes, and prior myocardial infarction to twenty-five year mortality for the 361,662 men screened. Aim 3 will relate insulin-like growth factor 1 (IGF-1), IGF binding protein, and fasting and one-hour glucose measurements from frozen baseline sera to mortality for the 12,866 men randomized.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': False, 'eligibilityCriteria': 'No eligibility criteria'}, 'identificationModule': {'nctId': 'NCT00011206', 'briefTitle': 'Mortality Follow-Up and Analyses of Men in the MRFIT', 'organization': {'class': 'OTHER', 'fullName': 'University of Minnesota'}, 'orgStudyIdInfo': {'id': '963'}, 'secondaryIdInfos': [{'id': 'R01HL068140', 'link': 'https://reporter.nih.gov/quickSearch/R01HL068140', 'type': 'NIH'}]}, 'contactsLocationsModule': {'overallOfficials': [{'name': 'James Neaton', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Minnesota'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Minnesota', 'class': 'OTHER'}, 'collaborators': [{'name': 'National Heart, Lung, and Blood Institute (NHLBI)', 'class': 'NIH'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
