title: Data to assess the generalizability of samples from studies of adult smokers.
abstract: BACKGROUND
  One major determinant of external validity is the representativeness of the sample. This article provides data to help authors and readers assess the generalizability of samples from smoking studies
  
  
  METHODS
  We analyzed the 2007 U.S. National Health Interview Survey.
  
  
  RESULTS
  We provide means, SEMs, and 95% CIs for demographic and smoking behavior characteristics of never-smokers, ever-smokers, all current smokers, current daily smokers, current nondaily smokers, long-term ex-smokers, and smokers who made a quit attempt in the last year.
  
  
  CONCLUSIONS
  Our results can help studies assess generalizability, set targets for recruitment, or reweigh data to reflect U.S. averages.
