Scatter plot and estimated linear regression equation. Scatter plot and estimated regression equation as a result of linear regression analysis of post-treatment irradiated kidney volume in percent with V24 are shown. Dashed lines represent 95 % confidence bands. The simple linear regression equation is as follows: Estimated post-treatment irradiated kidney volume (%) = 111.4–0.659 * V24 (%) + ε. Epsilon is the error term and its standard deviation is 6.43. The coefficient of determination was 0.60 (p < .01)
