Table 2.
Examination of the model (seven variables to be forced in + additional lipid profiles)
| Variables added | -2LL_0 | -2LL_1 | AIC | -2(LL_0-LL_1) | df | p-value |
|---|---|---|---|---|---|---|
| LDL cholesterol | 122,330.5 | 122,296.4 | 122,314.4 | 34.06 | 1 | < 0.001 |
| HDL cholesterol | 122,179.5 | 122,197.5 | 150.98 | 1 | < 0.001 | |
| TG | 122,264.3 | 122,282.3 | 66.16 | 1 | < 0.001 | |
| TG/HDL cholesterol ratio | 122,265.5 | 122,283.5 | 64.96 | 1 | < 0.001 |
Seven variables; age, sex, body mass index, systolic blood pressure, fasting plasma glucose, smoking habits, and physical exercise
LDL, low-density lipoprotein; HDL, high-density lipoprotein; TG, Triglycerides
-2LL_0; The -2 log likelihood of the model with the 7 variables to be forced in as main effects
-2LL_1; The -2 log likelihood of the model with the above 7 variables + additional lipid profiles
-2(LL_0-LL_1); Test statistic
df; Degrees of freedom of the test statistic (difference in the number of parameters)
