Fig. 3From: Simultaneous integrated boost (SIB) to dominant intra-prostatic lesions during extreme hypofractionation for prostate cancer: the impact of rectal spacersBox plots of targets’ a absolute doses [Gy] achieved for pre- and post-spacer plans, b percentage volumes of the CTVpb, Tpsv, and PTVpsv receiving specified prescription doses. The median values are indicated by the central line within the box, and the edges of the box represent the inter-quartiles range, the minimum, maximum values (excluding outliers; any values over 1.5 times the interquartile range over the 75th percentile or any values under 1.5 times the interquartile range under the 25th percentile) are represented by the whiskers, and the outliers are plotted as individual points. p values < 0.05 are considered significantBack to article page
