• CC = correlation coefficient for smoking prevalence and each variable.

• 1-150 Smoking prevalence = (daily smoker + occasional smoker)/number of responders. Prevalence in each hospital is age-adjusted using total subjects as a standardised population.

• 1-151 Patients = inpatients + outpatients.

• 1-152 Population = population of municipality where each hospital is located.

• 1-153 Using null hypothesis that correlation is equal to zero.
