Summary of the results obtained by analyses (ANCOVA and logistic regression analysis) for the relationships of smoking with lipid-related indices and the variables comprising these indices
| Variables | Nondrinkers | Drinkers | Overall subjects | |||

| Triglycerides | ↑ | ↑ | ↑ | ↑ | ↑ | ↑ |
| HDL-C | ↓ | ↓ * | ↓ | ↓ * | ↓ | ↓ * |
| LDL-C | ↑ | ↑ | ↓ | → | → | ↑ |
| LDL-C/HDL-C | ↑ | ↑ | ↑ | ↑ | ↑ | ↑ |

Results of ANCOVA (A, comparison of means of each variable between nonsmokers and smokers) and logistic regression analysis (L, comparison of frequencies of abnormality in each variable between nonsmokers and smokers) are shown in the left and right sides, respectively, of each cell in the table.↑, higher in smokers than in nonsmokers; ↓, lower in smokers than in nonsmokers; →, not different in smokers and nonsmokers. *: “↓” here indicates higher frequency of hypo-HDL cholesterolemia. WC, waist circumference; WHtR, waist-to-height ratio; 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
