Percent error in predicted 2004 ventricular volume from two models of ventricular expansion. One model predicts 2004 volume using a regression line fit to 1998 and 2002 ventricular volumes (“Model WITHOUT Covariates”). The other model uses clinical covariates to modulate the volume predicted by the regression line (“Model WITH Covariates”). Boxes show the median and first and third quartiles; whiskers extend to the most extreme data point which is no more than 1.5 times the interquartile range from the box. Raw values of ventricular acceleration are shown, with no adjustment for terms from statistical models.
