4. Fig 3
Progression of echocardiographic autograft regurgitation over time. For each patient the linear regression line that reflects the progression of echocardiographic aortic valve regurgitation over time is presented. The bold line represents the overall progression of echocardiographic regurgitation of the whole autograft group over time, which can also be described as yt = *t (yr = regurgitation at time t).
