Correlation coefficients (c) between measurements of different lipid-related factors
| Same sample (9805) | Different sample (2 × 1042) | |
|---|---|---|
| Within LDL particles | ||
| ApoB vs. LDL-C | 0.85 | 0.68 |
| Within HDL particles | ||
| ApoA1 vs. HDL-C | 0.70 | 0.64 |
| Between LDL and HDL particles | ||
| ApoB vs. apoA1 | 0.09 | −0.06 |
| ApoB vs. HDL-C | −0.22 | −0.20 |
| ApoB vs. HDL-C/apoA1 | −0.39 | −0.25 |
| LDL-C vs. apoA1 | 0.06 | 0.00 |
| LDL-C vs. HDL-C | −0.06 | −0.08 |
| LDL-C vs. HDL-C/apoA1 | −0.13 | −0.13 |
| LDL-C/apoB vs. apoA1 | −0.04 | 0.11 |
| LDL-C/apoB vs. HDL-C | 0.24 | 0.18 |
| LDL-C/apoB vs. HDL-C/apoA1 | 0.39 | 0.17 |
The standard error of each c, estimated as (1 − c2)/√N, is <0.022. Same sample: all 9805 controls in the present study. Different sample: 1042 controls with re-measurement 2–3 years later (yielding two independent estimates of each correlation coefficient; their average is tabulated).
