Table 3 Characteristics of 35 nondiabetic rheumatoid arthritis patients (29 women, 11 with hypertension, 10 with dyslipidaemia, 11 smokers) who were matched 1:1 with 'healthy' control subjects for sex, age (59.6 ± 11.4 years) and other traditional cardiovascular risk factors present both at baseline and at follow-up enda

  1. 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.
