Logistic regression analyses to assess associations of lipoproteins and their subclasses with high vs. low adiponectin levels in the HVs and patients with MS. The results are presented as odds ratios (ORs) and 95% confidence intervals (CI) per increase in one unit (mg/dL) of (A) the LDL and (B) HDL parameters. The x-axis is presented on a log-2 scale. p-values < 0.0005 are considered statistically significant after Bonferroni correction for multiple testing. Significant parameters as well as their respective ORs and 95% CIs are depicted in red. In the MS patients, the parameters, ORs, and 95% CIs depicted in purple are those with the highest VIP scores in the OPLS-DA. apoA-I, apolipoprotein A-I; apoA-II, apolipoprotein A-II; apoB, apolipoprotein B; C, cholesterol; CI, FC, free cholesterol; HDL, high-density lipoprotein; HV, healthy volunteer; LDL, low-density lipoprotein; MS, metabolic syndrome patient; OPLS-DA, orthogonal partial least-squares discriminant analysis; PL, phospholipid; VIP, variable of importance projection.
