aBMI: body mass index, CV: cardiovascular, DBP: diastolic blood pressure, hs-CRP: high-sensitivity C-reactive protein, LDL: low-density lipoprotein, SBP: systolic blood pressure. Paired t-tests and Wilcoxon tests were used for all comparisons of the matched groups as appropriate. Variables are expressed as mean ± SD or as median (lower and upper quartiles). Comparisons between subgroups after Bonferroni correction did not reach significance.
