Figure 4.

Pain scores recorded in the case report form (CRF) for the treated tumor for (a) 9 patients in the intraosseous group and (b) 12 patients in the extraosseous group. In each diagram, the horizontal lines show the mean ± SD scores, and a discrete marker shape is used to show the individual score for each patient at each time point. At days 30, 60, and 90 after treatment, scores were significantly lower than those in pretreatment (Pre Tx) for the intraosseous group but not for the extraosseous group. The P values have been corrected for multiple comparisons: P >1* indicates that the uncorrected P value was already >0.34. NRS = numerical rating scale.
