†For Stranraer, Scotland study,31–34 cessation community is Stranraer, comparison community is Annan.
‡For Tiel, Netherlands study,38 cessation community is Tiel, comparison community is Culemborg.
§For the East Germany study,25 cessation community is Chemnitz, comparison community is Plauen. Furthermore, for this study, only an overall sample size per year was provided (not broken down by age). Values in this table were determined by dividing the n for each year by the number of age groups (10); for the combined groups, the value is halved.
