Longitudinal changes in the RF time series parameters in the responding tumors. Bar graph summarize the fold changes of six RF time series parameters compared with baseline. *P < 0.05, ** P < 0.01, *** P < 0.001 for comparison between control and treated tumors. The parameters were shown as medians and 25th~75th percentiles
