Fig. 4

A box plot of HD95 values for the CTVin between dCT and pCT across all fractions for each patient (n = 29) with CBCT (a) and initial SGRT setup (b). The red line and the blue boxes indicate the median and 25th and 75th percentiles, respectively. The whiskers extend to the smallest and largest values within 1.5 times the interquartile range measured from the 25th and 75th percentiles, respectively. Outliers are marked with a plus sign.
