Note: Results expressed as mean ±SD: sex, age, weight, BMI (body mass index), WC (waist circumference), HC (hip circumference), WHR (waist to hip ratio), SMM (skeletal muscle mass); body fat, body fat, MBR (basal metabolic rate); Results expressed in number (percentage): diabetes, HOMA (homeostasis model assessment insulin resistant), dyslipidemia, hypertension, hypothyroidism, alcohol abuse, picky eater; Results expressed as median (25/75 percentile): NpacY (number of pack-years), N cigarettes/day (number of cigarettes/day) age of onset, smoking period.Discrete variables analyzed by Pearson or Fisher chi-square test; continuous variables analyzed by Student t test and ANOVA test with Bonferroni correction (for multiple comparisons).Values in bold = statistic significant (pClinical and demographic profile of the sample stratified by smoking status.

注：结果表达方式如下：以均值±标准差（mean ± standard deviation, SD）表示的指标包括性别、年龄、体重、BMI（body mass index，体重指数）、WC（waist circumference，腰围）、HC（hip circumference，臀围）、WHR（waist to hip ratio，腰臀比）、SMM（skeletal muscle mass，骨骼肌质量）、体脂及MBR（basal metabolic rate，基础代谢率）；以例数（百分比）表示的指标包括糖尿病、HOMA（homeostasis model assessment insulin resistant，稳态模型胰岛素抵抗评估）、血脂异常、高血压、甲状腺功能减退症、酒精滥用及挑食行为；以中位数（25/75百分位数）表示的指标包括NpacY（number of pack-years，吸烟包年数）、每日吸烟支数、发病年龄及吸烟时长。分类变量采用Pearson卡方检验或Fisher确切概率法分析；连续变量采用Student t检验及经Bonferroni校正的方差分析（ANOVA）进行多重比较。加粗数值代表具有统计学显著性（P<0.05，另有说明者除外）。本数据集为按吸烟状态分层的样本临床与人口学特征。
