Scatter diagram of HA and CK plans in V4Gy, V10Gy, V12Gy, V23Gy with tumor volume as y axis showing that parameters have a correlation with tumor volumes. Blue spots represent the HA plans and red spots represent the CK plans. And by a spearman bivariate correlate analysis, the D-value of two parameters with tumor volume are 0.55, 0.81, 0.82, 0.90, respectively
