The relationship between FRS and eGFR_CKD-EPI in all participants.

<p>X-axis represents eGFR_CKD-EPI (estimated glomerular filtration rate calculated by CKD-EPI equation); Y-axis represents FRS (Framingham global CVD risk score); r1 and r2 represents the Pearson correlation coefficient between FRS and eGFR_CKD-EPI calculated in 2008 and in 2011; P1 and P2 represents <i>P</i> value of 2008 and 2011; thin straight line and thin dotted lines represent the regression line and its 95% confidence interval of 2008; bold straight line and bold dotted lines represent the regression line and its 95% confidence interval of 2011.
