Comments to table 1-S Comparison of HT and NT (normotensive) RA and OA patients In both RA and OA patients, the HT subgroup was characterized by older patients and a higher proportion of the elderly, a longer duration of the disease (RA or OA), higher BMI and a greater proportion of overweight/obese patients, higher VASP, a higher proportion of dyslipidemic and DM patients and higher plasma LDL and triglyceride concentrations, compared with the NT patients. VASGH and HDL values were similar in HT and NT in both RA and OA patients. The following variables had dissimilar differences between HT and NT patients in RA and OA: the proportion of female HT and NT patients was similar in the RA group, but higher in the HT patients of the OA group; WHR was higher in HT RA patients than in NT RA patients, but similar in HT and NT OA patients; ESR, CRP, Chol, LDL, and Glc concentrations were higher in HT than in NT patients in the RA group, but were similar in the HT and NT patients in the OA group. (Statistically significant difference for CRP in OA was so small that had no clinical significance). Regarding variables measured only in the RA group, DAS28-CRP values and RF concentration were similar in the HT and NT patients, whereas HAQ was higher in the HT than in the NT patients. Comparing HT and NT patients regarding smoking the HT group had a higher proportion of nonsmokers, a similar proportion of ex-smokers, and a lower proportion of current smokers than did the NT group for both RA and OA. The smoking duration of ex-smokers was similar in among the HT and NT patients with RA and with OA. For current smokers, the duration of smoking was similar and the number of cigarettes per day was higher in HT RA patients than in NT RA patients and lower in HT OA patients than in NT OA patients. Regarding medications there were no statistically significant differences in the proportions of users of non-steroidal anti-inflammatory drugs (NSAIDs) between HT and NT patients in either the RA or OA group. The same was found for RA-specific medication, including various disease modifying anti-rheumatic drugs (DMARDs), glucocorticoids (GCs) and anti-tumor necrosis factor (anti-TNF) drugs. An exception to this finding was leflunomide, with a higher proportion of users in HT group and the use was associated with a higher prevalence of HT. than in nonusers (69.4 in users % vs. 58.1%, , P=0.048). Regarding GCs, only the duration of therapy was associated with HT; duration was longer in HT than in NT patients. The proportions of antihypertensive users, in terms of their general use and in terms of specific drugs, were higher in OA HT patients than in the RA HT patients, except in the case β- 7 blockers and angiotensin-II receptor antagonists, which were used by similar proportions of patients in both groups. Statins were used by a higher proportion of HT than NT patients in both the RA and OA groups, and the proportion of HT users was higher in OA than in RA patients. Comparison of hypertensive RA and OA patients The HT OA subgroup was characterized by higher age, a greater proportion of elderly patients, longer awareness of HT, higher BMI, a greater proportion of overweight/obese patients, a higher proportion of dyslipidemic and DM patients, and higher TG and Glc concentrations compared to HT RA patients. In contrast, the disease duration (RA or OA) was longer and ESR, CRP and LDL concentrations were higher in HT RA than in HT OA patients. The proportion of females, WHR, VASP, VASGH and Chol, HDL and creatinine concentrations were similar in HT RA and OA patients. 8
