I requested 1987 NHIS data in my extract, and I see a sample size with smoking data that matches that of the Cancer Epidemiology Supplement. But I’m not getting a sample size that would lead me to believe the Cancer Control Supplement is included. Or were these 2 supplements administered to the same group of participants that year?
Is the Cancer Control Supplement included in 1987 NHIS data? Or just the Cancer Epidemiology Supplement?
