Figure 1. Hazards Ratios for Incident Cardiovascular Event.
Hazards ratios for incident cardiovascular events in 2,405 individuals initially free of clinical cardiovascular disease are stratified by quartiles of brachial (hatched bars) and central aortic (solid bars) PPs. Quartiles of central PP (p<0.001) predicted outcome more strongly than quartiles of brachial PP (p=0.052). Only the event rate in the fourth central PP quartile (PP ≥50 mmHg) was significantly higher than in the first quartile (p=0.003).
