Henry Ford's findings mirror the results of several similar studies. In 2007, a study found an 8 percent reduction in hospital admissions one year after the state of New York implemented a public smoking ban. Studies in several European countries had similar results.
Henry Ford researchers used a statistical method called meta-analysis to calculate the impact of a smoking ban and hospital admission incidence. Researchers used the average rate of hospital admissions for heart attack for the past eight years, then multiplied that rate with the attributable risk calculated from several studies -- two in Italy, one in Scotland and one each in Montana, Colorado and New York -- to estimate the projected rate of heart attack admissions in Michigan if a smoking ban was enacted.
