Project description:The Subpopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS) (ClinicalTrials.gov Identifier: NCT01969344) includes 2,771 subjects, aged 40-80 years with at least 20 pack-years of smoking. An additional 202 subjects were never smokers. Fasting blood drawn at the enrollment visit using a p100 tube. The first 649 subjects who returned for a 5-7 year visit (Visit 5) were selected for this study. The blood profiled were from the year 1 visit.
