Structure

Source: Tobacco smoke (secondhand smoke)
Factor: Nicotine
Setting: hospital, AM
Study design: before-and-after study at the national oncology hospital in Armenia: indoor fine particulate matter and air nicotine measured before and after a three-part intervention to improve compliance with the hospital smoke-free policy, with staff surveys alongside (class 4)
Effect: median
Caveat: geometric means recorded under measure median; the intervals overlap, so the fall in nicotine is not established by this sentence
