Online Appendix figure 3. Sensitivity analyses: standardized differences of adiposity markers in relation to adjusted blood pressure level, assuming the average effect of treatment is approximately half the size estimated by Law et al[21].
Estimated blood pressure differences related to 1 SD (standard deviation) difference of each adiposity marker (second column) are based on linear regression models, adjusted for age, gender, estimated glomerular filtration rate (eGFR based on the MDRD score), current smoking status, and history of coronary artery disease, cerebrovascular disease, peripheral artery disease, and abdominal aortic aneurysm. Observed blood pressure was adjusted by adding 5/2.5 mmHg and 2.5/1.25 mmHg for the first and every subsequent class of blood pressure lowering medication used. * indicates significant difference (p<0.05) between men and women.
Online Appendix figure 4. Sensitivity analyses: standardized differences of adiposity markers in relation to adjusted blood pressure level, disregarding beta- blocker use.
Estimated blood pressure differences related to 1 SD (standard deviation) difference of each adiposity marker (second column) are based on linear regression models, adjusted for age, gender, estimated glomerular filtration rate (eGFR based on the MDRD score), current smoking status, and history of coronary artery disease, cerebrovascular disease, peripheral artery disease, and abdominal aortic aneurysm. Observed blood pressure was adjusted by adding 10/5 mmHg and 5/2.5 mmHg for the first and every subsequent class of blood pressure lowering medication used.
Beta-blocker use was disregarded because of the questionable impact of beta-blockers on blood pressure level[22]. * indicates significant difference (p<0.05) between men and women.
