Control data from a large-scale case-control study of tobacco-related diseases were analyzed to characterize variables associated with cigarette preference (or type of cigarette smoked). Age, sex, race, education, and religion were found to have a strong influence on the choice of cigarette according to tar and nicotine yield. Data on the amount and duration of cigarette smoking also were evaluated by brand history to determine whether tar yield was associated with these variables. Women smoking cigarettes in the low-tar categories tended to smoke fewer cigarettes per day than women smoking cigarettes in the higher tar categories. A similar trend was not found for men. As might be expected, only 2% of the men and 3% of the women over the age of 40 smoked low-tar cigarettes (less than 10 mg tar) for 10 years or more.
对一项关于烟草相关疾病的大规模病例对照研究的对照数据进行了分析，以确定与香烟偏好（或所吸香烟类型）相关的变量。研究发现，年龄、性别、种族、教育程度和宗教信仰对根据焦油和尼古丁含量选择香烟有很大影响。还通过品牌历史评估了吸烟量和吸烟时长的数据，以确定焦油含量是否与这些变量相关。吸低焦油类香烟的女性每天吸烟的数量往往比吸高焦油类香烟的女性少。男性未发现类似趋势。不出所料，40岁以上的男性中只有2%、女性中只有3%吸低焦油香烟（焦油含量低于10毫克）达10年或更长时间。
