Table 4.
R-squared values, and corresponding F-tests in various models that evaluated the explanatory ability of body composition parameters towards Lp-PLA2 activity.
| Initial model: | R2 | F | P |
| LDL-cholesterol, age, smoking, physical activity | 0.296 | 4.098 | 0.007 |
| Additive models (initial + one of the following variables): | R2 change* | F | P |
| DXA ROI fat | 0.136 | 9.076 | 0.005 |
| Arms fat | 0.118 | 7.678 | 0.009 |
| Trunk fat | 0.114 | 7.316 | 0.010 |
| Total body fat | 0.084 | 5.152 | 0.029 |
ROI: Region of interest; DXA: dual energy X-ray absorptiometry.
The other anthropometric variables tested did not have a significant additive explanatory effect on Lp-PLA2 activity.
* The change in R-squared values between the additive and the initial models.
