Odds ratios of smokers vs. nonsmokers for high lipid-related variables in interaction analysis and sensitivity analysis

	Interaction analysis	Sensitivity analysis
Large WC	0.92 (0.72–1.18)	1.04 (0.87–1.23)
High WHtR	1.00 (0.85–1.17)	0.90 (0.80–1.01)
High triglycerides	1.05 (0.85–1.31)	1.40 (1.20–1.64)**
Low HDL-C	0.86 (0.69–1.07)	1.73 (1.51–1.98)**
High LDL-C	0.71 (0.57–0.87)**	1.29 (1.12–1.48)**
High LDL-C/HDL-C	0.88 (0.57–1.36)	2.19 (1.71–2.80)**
High TG/HDL-C	1.00 (0.75–1.34)	1.68 (1.39–2.04)**
High LAP	0.92 (0.79–1.09)	1.21 (1.07–1.36)**
High CMI	0.94 (0.80–1.10)	1.45 (1.29–1.63)**

Shown are odds ratios with their 95% confidence intervals in parentheses. Age and history of regular exercise were used as other explanatory variables. In interaction analysis, the interaction term consisting of smoking and alcohol drinking was added to the explanatory variables, and odds ratios of the interaction term were estimated in overall participants. In sensitivity analysis, odds ratios of light smokers vs. nonsmokers were estimated in nondrinker subjects. WC, waist circumference; WHtR, ratio of waist circumference to height; HDL-C, HDL cholesterol; LDL-C, LDL cholesterol; LDL-C/HDL-C, ratio of LDL cholesterol to HDL cholesterol; TG/HDL-C, ratio of triglycerides to HDL cholesterol. Asterisks denote significant differences from the reference level of 1.00 (**, p < 0.01)
