Estimated central systolic blood pressure (cSBP) and amplification (Brachial SBP-cSBP) are non-invasive measures potentially prognostic of cardiovascular (CV) disease. No worldwide, multiple-device reference values are available. We aimed to establish reference values for a worldwide general population standardizing between the different available methods of measurement. How these values were significantly altered by cardiovascular risk factors (CVRFs) was then investigated.

Existing data from population surveys and clinical trials were combined, whether published or not. Reference values of cSBP and amplification were calculated as percentiles for ‘Normal’ (no CVRFs) and ‘Reference’ (any CVRFs) populations. We included 45 436 subjects out of 82 930 that were gathered from 77 studies of 53 centres. Included subjects were apparently …
