^aSubjects were divided into younger age group and older age group according to the median age (63 years old).^bQuit smoking and still smoking were considered to have a history of smoking while never smoking was considered as no smoking history. Like smoking history, quit drinking and still drinking were considered to have a history of drinking while never drinking was considered as no smoking history. Two independent sample t tests or analysis of variance (ANOVA). Nonparametric rank sum Z test (Mann-Whitney test).
