Figure 1. An average number of daily steps normalized to the patient activity level prior to the radiotherapy.

The numbered steps prior to and after the radiotherapy (RT) taken by the patients were normalized to the average number of daily steps taken by the patients prior to the RT. Comparison of the daily activity level of the patient prior to (pre-RT) vs. after RT (seven days post-RT) were made using the Wilcoxon signed-rank test. Error bars represent standard error of the means.
